Marrying a well-settled but divorced guy

It seems that he wanted something and didn’t really think of the consequences - surely he must have known that she liked to party and was not very domesticated. If he is Muslim, did she convert for him, or was she already a Muslim when they met? Did she even convert? If you meet someone in that environment its very difficult to change them. I have a colleague who is very outgoing - her hubby doesn’t like it but he has just learnt to accept it because he feels there is nothing he can do to stop her.
