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’d work on processing my feelings and sorting them into helpful to express, necessary to express, and unhelpful and unnecessary to express
Do you trust your daughter’s ethics and willingness to prioritize her happiness? If not that should be your concern, otherwise learning to trust her to leave if anything goes as wrong as it likely will is something to focus on.
Regardless of everything, therapy is probably a good call for you. It’s not just for the mentally ill, it’s also a resource to help deal with it when life throws you a curveball.
