This suit was originally brought in the District Court of Montgomery County by Mrs. Dickson Falvey against Mrs. Ruby E. Falvey, individually and as independent executrix of the estate of her deceased husband, Thos. S. Falvey, and as trustee, W. A. Evans as independent executor of the estate of Thos. ’ S. Falvey, deceased, Paul Falvey also as independent executor of such estate, Tom Seymour Falvey, Jr., Olive Seymour Falvey and Sue Falvey Sims, a feme sole. This suit was filed in June, 1948, and thereafter in August, 1948 the original plaintiff, Mrs. Dickson Falvey, *467died and Sue Falvey Sims, a feme sole, daughter and only surviving heir of Mrs. Dickson Falvey substituted herself as plaintiff in suit and made as defendants, Mrs. Ruby E. Falvey, individually and as independent executrix of Thos. S. Falvey, deceased, and as trustee; Tom Seymour Falvey, Jr., a minor; Olive Seymour Falvey, a feme sole; and Houston- Bank & Trust Company as executor and trustee of the will and estate of Thos. S. Falvey, deceased. The suit was founded upon the breach of a written property settlement agreement made in contemplation of a divorce between Dr. Thos.. S. Falvey and his first wife, Mrs. Dickson Falvey, on August 1, 1919. The suit, was brought primarily to recover an .undivided one-half interest in certain property that had been acquired by Thos. S. Falvey, deceased, in his lifetime and in the alternative to recover certain sums of money due under the property settlement agreement. At the conclusion of the testimony both plaintiff and all defendants moved the court for an instructed verdict. The court discharged the jury, however, and entered judgment denying the plaintiff Sue Falvey Sims any recovery under her principal cause of action and rendered judgment in her favor against Mrs. Ruby E. Falvey and Houston Bank & Trust Company as independent executrix and executor of' the estate, for the sum of $1,592.48. Mrs. Sue Falvey Sims, the plaintiff in the trial court, has duly perfected her appeal to this court for review of such judgment.
Dr. Thos. S. Falvey and Mrs. Dickson Falvey, the original plaintiff in this suit, were married in 1900 and were divorced in September, 1919. On the day following the date of the divorce Dr. Falvey married Mrs. Ruby E. Falvey and their marriage continued until March 16, 1948, the date of Dr. Falvey’s death. Mrs. Sue Falvey Sims, the plaintiff in the trial below and the appellant here, was the only daughter of the first marriage and Thomas Seymour Fal-vey, Jr., a minor, and Olive Seymour Fal-vey are the only two children, of the second marriage. During the existence of Dr. Falvey’s second marriage he and his second wife accumulated a large community estate. The parties stipulated that' all of the property in p'ossession óf Dr. Falvey and all the property which was conveyed by the two trust agreements' which Dr. Falvey and Mr's. Ruby E. Falvey executed for the benefit of their two children was acquired on dates subsequent to the date of their marriage.
The appellant' sought by her principal cause of action to recover an undivided one-half interest in all property claimed by Dr. Thos. S. Falvey and Chis second wife, Ruby E. Falvey, as community property and also sought to recover an undivided one-half interest in the two trust funds created by Dr. Falvey and Ruby E. Falvey for the benefit of their two children. This principal recovery was sought upon the theory that Dr. Falvey breached the property settlement agreement made with his first wife, Mrs,, Dickson Falvey; that under the terms of this agreement this breach gave her the option of terminating the agreement and recovering her one half interest in the community property which he had acquired under it, in trust, and conditioned upon his full performance of such contract; that Dr. Falvey had inextricably commingled . the community property of the first marriage which he acquired under . the settlement agreement with the community property of the second marriage, and the trust funds were created out of the commingled estates; and that by reason of such commingling the defendants below had the burden upon the trial of separating the commingled property and identifying any part thereof that they might be entitled to retain, and that such defendants had wholly failed to discharge this burden.
On August 13, 1919, .in contemplation of a divorce thereafter to- be secured, Mrs. Dickson Falvey and Dr. Thos. S. Falvey executed the following contract, which is the basis of this lawsuit:

“Witness the hands of the parties this 13th day of August, A.D. 1919.
“(s) Thos. S. Falvey
“(s) Mrs. Dickson Falvey”
About a month before the above contract was signed, Dr. Falvey had conveyed to Mrs. Dickson Falvey the property referred to in the contract as the San Benito property. Under the contract Dr. Falvey was to receive all the income from this property, on which was situated a hotel. This property was later sold by Mrs. Falvey and from the evidence it is apparent that Dr. Falvey consented to such sale and assisted in the details of the consummation of the sale. The money received from the sale was invested by Mrs. Dickson Falvey. At first this arrangement seemed to be satisfactory with Dr. Falvey but at a later date he showed himself to be dissatisfied because he had not received the income from the investment of the money received from the 'sale. For approximately 18 years before the suit was filed Dr. Falvey did not pay the $350 per month which he undertook to do in the marriage settlement agreement. He sent her $100 per month instead of the $350, beginning some time in 1929. These $100 per month payments ceased in December, 1947, and it is for the period of time from that date until the death of Mrs. Dickson Falvey in August, 1948, that the trial court allowed recovery of $100 per month against the executrix and the executors of Dr. Falvey’s will and estate. The balance of the sum *470awarded to the appellant in the judgment of the trial court represented the value of a policy loan and the amount of unpaid premiums' due on a life insurance policy of Dr. Falvey.
There is no evidence in the record tracing any of the community property of Dr. Falvey’s first marriage into any specific property belonging to the community estate of Dr. Falvey’s second marriage. The appellant contends that this fact is sufficient to make it incumbent upon the trial court and upon this court upon appeal to enter judgment in her behalf against all of the appellees for an undivided one-half interest in all community property of the second marriage. She contends that since the burden was upon Dr. Falvey to maintain records and accounts from which such property might be identified and traced and no such records were kept and no such evidence was produced by the appellees, then all of the property of the second marriage is impressed with a trust for the benefit of Mrs. Dickson Falvey, the first wife and appellant here who, as her only heir, is substituted as plaintiff. She relies upon the case of Eaton v. Husted, 141 Tex. 349, 172 S.W.2d 493, by the Commission of Appeals, the opinion in which case was adopted by the Supreme Court.
Appellees with equal vigor declare that this -same fact is sufficient to require the trial court to enter judgment in their favor, denying the appellant any relief under her principal cause of action and likewise requires an affirmance by this court of such a judgment. They rely upon the case of Logan v. Logan, 138 Tex. 40, 156 S.W.2d 507.
Introduced in evidence on trial were a great many letters from Dr. Falvey to his daughter, from which it is evident that Dr. Falvey engaged in many different types of business transactions. He was a physician and surgeon by profession and was a partner in the operation of the hospital, he also was engaged in the hotel business, oil business, banking business, lumber business and bought and sold land at different times. There were also letters in evidence passed between Mrs. Dickson Faivey, the original - plaintiff, and Dr. Falvey. From the evidence we are satisfied that the-commingling of funds and property by Dr.. Falvey, which he took under the- contract, with the community funds and property accumulated by him and his second wife-was not a wrongful commingling, of funds- and property. The entire course , of his dealings in the handling of the - property seems to have been that which was contemplated by both parties to the contract when Mrs. Dickson Falvey agreed by the contract to convey and did convey to> him-, all of her interest in their community property, and Dr. Falvey agreed, among other things, to pay her $350 per month for the balance of her life. In all the correspondence between them, as shown by the evidence, there is no hint or intimation-on the part of Mrs. Dickson Falvey that she had any complaint to make in regard to such method of handling and commingling of the property and funds by Dr. Falvey, but such correspondence "evidences complete agreement and acquiescence in such method of handling the community property and funds by Dr. Falvey.. The commingling of funds and property by Dr. Falvey therefore was not a wrongful commingling under the principle of law announced in Chief Justipe Alexander’s, opinion in the case of Logan v. Logan, supra. In this case, since the commingling was done rightfully and with the consent of Mrs. Diclcson Falvey, no presumption is raised that the entire community estate of Dr. Falvey and Mrs. Ruby Falvey is subj ect to a trust for the benefit of Mrs.. Dickson Falvey and her daughter, plaintiff here, and consequently the burden was on the plaintiff below, appellant here,, to trace any funds or property of the-community estate received by Dr Falvey under the separation contract into some-specific property accumulated by Dr. Falvey and Mrs. Ruby Falvey. We believe the facts of this case, bring it squarely within the rule announced in Logan v. Logan, supra, and not by the case of Eaton v. Husted, supra. It follows, therefore, that since the appellant wholly failed to> discharge her burden of proof in tracing the community property of the first marriage *471into the community property of the second marriage, the trial court was correct in denying the appellant any recovery on her principal cause of action.
By her alternative cause of action, the appellant sought to recover the $350 monthly payments due under the contract during the period beginning" 4 years prior to the institution of the suit and ending at the time of Mrs. Dickson Falvey’s death in 1948, less credit for the payments of $100 per month made by Dr. Falvey to Mrs. Dickson Falvey through November, 1947, plus approximately $3,700 which Mrs. Dickson Falvey claimed she would have received under the contract but for Dr. Falvey’s default in failing to keep such insurance in force as he agreed. This action of the trial court is assailed by the appellant under her Point No. 2. In her brief and reply briefs the matter of receiving the sum of money which she would have received from insurance is not briefed and we consider it waived. As to the $350 monthly payments due under the contract, however, it is noted that the only defenses urged by the appellees to her cause of action were that (1) Mrs. Dickson Falvey had breached the original contract by selling the San Benito hotel property and retaining the proceeds of the sale and thereby excused the appellees from further performance; (2) the 2 and 4 years statutes of limitation; (3) Mrs. Dickson Falvey released Dr. Falvey from the marriage settlement contract and said contract was abondoned by both parties. From the various letters and other matters in evidence, it is evident that Dr. Falvey assisted in making both sales of the San Benito hotel property. The property was first sold to a Mr. Robards in 1920, and it was repossessed for failure to make the agreed preferred payments, and in 1925 Mrs. Dickson Falvey again conveyed the property to F. B. Sub-lett, et al. Dr. Falvey took an active part in all the negotiations leading to the consummation of both sales and continued to make the $350 per month payments thereafter until 1929. This transaction, we are satisfied, could in no way be considered as a breach of the marriage settlement contract by Mrs. Dickson Falvey so as to release Dr. Falvey from its terms. He did not so regard it as is shown by his continuing to make payments until the year of 1929.
We are also satisfied that the evidence does not show as a matter of law, that Mrs. Dickson Falvey released Dr. Falvey from the marriage settlement contract or that said contract was abandoned by both parties. It is clear from the letters which she wrote to him during her lifetime that she felt herself physically unable to begin and carry on litigation over the contract, but that she still regarded the $350 monthly payments as due and owing her, although she accepted the $100 monthly payments from Dr. Falvey. Occasionally in such letters there appears the reminder that consequences of a lawsuit over this contract could be surprising and serious. In one letter dated March 4, 1946, Mrs. Dickson Falvey wrote that “I do know that when you ceased to make the payments to me that my right to community property claim was immediately revived”. The .appellees maintain that such a statement by her fixed the date when limitation began to run • against her claim as the date when Dr. Fal-vey ceased to make the $350. payments in 1929. We do not so regard it. Under the authority‘of Matlock v. Gulf C. & S. F. Ry. Company, Tex.Civ.App., 70 S.W.2d 279, and cases cited, we believe that the rule is settled in this state that a cause of action for damages for a breach of a lifetime contract accrue when there is a positive and absolute refusal on the part of the ■person agreeing to pay to perform his promise to pay and the other party elects to treat the contract as breached. In this case we do not see that the actions and conduct ,of Mrs. Dickson Falvey after Dr. Falvey’s breach of the contract in ■ 1929 show, as a matter of law, that Mrs. Diokson Falvey elected to treat the contract as breached, although she believed the contract as a matter of fact had been breached by Dr. Falvey. She could have brought suit after the breach of 1929 but was not required to do so if she did not so desire, the only penalty for such failure to sue being the loss by limitation of such claims as became more than 4 years old before suit was *472brought. We believe, therefore, that Mrs. Dickson Falvey and the substituted plaintiff, appellant here, had th.e right to recover under the contract for a% of the $350 payments which were not barred by the 4 year statute of limitation, Vernon’s Ann.Civ.St. art. 5527, at the time the suit was filed, less a credit for the various $100 monthly payments received by her during such 4-year period. The judgment of the trial court denying the appellant any recovery under her alternative cause of action is therefore reversed and judgment here rendered in favor of the appellant, Sue Falvey Sims, and against the appellees, Mrs. Ruby E. Falvey and Houston Bank & Trust Company in their capacities as independent executrix and executor of the estate of Thos. S. Falvey, deceased for the sum of $13,100. This sum represents the $350' monthly payments for 4 years not barred by the 4 year statute of limitation, less the sum of $3,900 paid by $100 monthly payments to Mrs. Dickson Falvey during the 4-year period immediately before this suit was filed.
The appellant’s third point complains of the action of the trial court in awarding her the sum of $1,592.48 against the executrix and executor of the estate of her father for the reason that the trial court in its judgment based such recovery upon its finding and conclusion that Dr. Falvey and Mrs. Dickson Falvey had by their actions and conduct since 1929 substituted a new agreement for the old marriage settlement agreement, and that by such agreement he agreed to pay her $100 per month instead of $350. Both appellant and appellees urge in their briefs that this portion of the judgment should be set aside and held for naught. The appellant points out that no party to the lawsuit had urged by pleading or evidence that any new agreement was ever made between Dr. Falvey and Mrs. Dickson Falvey. There is no pleading to support such portion of the judgment. The appellant has ‘maintained throughout the trial that the old agreement was still in effect and the appellees have contended with equal insistence that the old contract had been breached, rescinded and abandoned and that Dr. Falvey had been released from its terms, and urged that Dr. Falvey had made the $100 monthly payments as a series of gifts rather than in discharge of any contractural obligation to Mrs. Dickson Falvey. The evidence, in the form of letters from Dr. Falvey to Mrs. Dickson Fal-vey, and other evidence in the record, do not show any new agreement between Dr. Falvey and Mrs. Dickson Falvey, but on the other hand show what could be more accurately described as a continuing disagreement. In view of the condition of the pleadings and the evidence, and because both appellant and appellees urge that such portion of the judgment be reversed, that portion of the trial court’s judgment which awarded the appellant the sum of $1,592.48 against Mrs. Ruby E. Falvey and Houston Bank & Trust Company as independent executrix and executor is reversed and rendered in favor of the appellees.
The judgment is in part affirmed and in part reversed and rendered.
