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.
Well if the that is case, there is no reason to compromise to have a relationship with your mom. Being with your dad is the way better option for you (since he loves you and you love him) and maybe it is the best option for everybody involved.
Still I hope you understand that at some level what your dad did was morally wrong. Irrespective how crappy things were, the correct order would have been to seek divorce before hooking up/dating somebody else. Learn from the mistake he made.
