My husband pays his adult daughter mortgage. She is married with 2 kids. Has a job but never has money.

We are married 22 years. My husband does things without asking me. He bought a condo for his daughter whom is grown. When he bought the condo she was separated from her husband. Since the purchase the hubs and his daughter have reconciled. I say he needs to stop paying the mortgage. He wont. She is a grown married women with a job and 2 kids. Her children wear nothing but the best clothes and she always has her nails done, hair done. Am I wrong for telling him he has to STOP paying this now. We have 4 children of our own. And he does not pay or buy them things. Our children know he does these things and resent him for this. I believe he feels guilty. Understand but enough is enough. She has not even called him in 7 months. Am I wrong to feel he needs to end this payment now.
