Bookie, what is more encouraging than a person who sees the best in you? This is what your daughter needs most from you. Not your money, dear you may need that for yourself!

Although I have no children, I was married and believe the husband's infedility (whether physical or emotional) is draining and she may want to confront him.

Child care is very expensive, I wonder if she could find something less expensive? For instance, there are many without jobs now that would appreciate an income. Perhaps she could find a woman willing to care for the children in their home and handle a few household chores for less?

p.s., keep the text messages and check into whether they can be saved if needed for legal purposes.
