My dad has recently been caught having an affair with his young personal assistant. Huge scandal; mom was very angry. Now they’re in the middle of divorce proceedings. Mom moved out, the other woman moved in and I chose to stay with him because we’re super close; he’s like my best friend. Now mom’s telling me to go and live with her and go no contact with him cause he’s a bad person and by continuing having a relationship with him I’m condoning his actions and “ignoring her suffering”. My relationship with my dad hasn’t changed, I don’t see why I should end it.
I think you should consider your mom is very hurt right now and my be overreacting by pulling you into the fight because of that. However, a cheater isn’t a good role model and neither is the destroyer of marriages. She got that right.
IMO you should suggest a compromise, like staying with him, but berating him and his mistress from time to time and should also be transparent about it, so they know it’s due punishment and a compromise for not leaving him.
