First of all, if nothing else, she divorced you, and she asked you for money and things, which shows that in her heart, you are at least reliable. In addition, it also shows that there is either no other man around her or that man is extremely unreliable.

Secondly, it still depends on whose fault the divorce is. It is normal to keep in touch if the two parties divorce only because of economic or trivial matters. If she betrayed you, you should stop helping her.

In addition, you also said that your own economy is relatively difficult, so you should start from both emotional and economic aspects. You failed her and tried your best to help her, but she failed you, and you tried your best to tolerate her death without help.
