Not a freak thread but my daughter caught her hubby wearing her undies and bra

She came home from work early..he was getting off. She said what the hell and he said he has been doing this since he was young using his moms panties. He told her he wants breast enhancements for himself but does not want to have sex with a man he claims he is not gay.
They have two young children. I think she should start a secret bank account and get ready to leave him.
They have been fighting for years and going to therapy for his porn addiction she does not mind porn but hates that he only looks at and watches transsexual porn men with breast and penises. He hides it but she finds it in the computer history he also is active in a forum of transsexual men.

This is the only forum I can ask this question at. What do you all think??
Looking for serious insight as this is a serious issue not a made up thread this is for real. My hubby set down and cried for daughter all she wants is a happy marriage with the man she loves..we don't see that happening they have been married 15 years and a lot of those years son in law has been mean to daughter and often calls her crazy...we are finding out the truth looks like he is the crazy one.

Over the years we have offered to pay for a divorce and throw a trailer on our land for her till she can get on her feet. She refuses to leave him so far.
