I’m gonna be honest, I’m not asking for a friend, I’m asking for myself. Our daughter (24) married this man (65) in September. She herself stated money was the main reason, and he knows it but it doesn’t bother him. Both my husband & I are having a very hard time getting used to the idea.
I’ll be very blunt: it’s her life and her decision. There is nothing to ‘manage’. You either accept it or you don’t, but if you don’t, there’s a good chance you will lose her.
I agree with you, I think OP means manage in the sense of managing themselves in this situation they clearly don’t like, not their daughter.
