Welcome to PC...

SilentlyScreaming posses some interesting questions and would just add these thoughts.

Please keep posting and talk to someone professionally...you are in the midst of a lot...

If so many people believe your dad is bad for your mom...is there some reason...did he cheat on someone? an old girlfriend? or your mom? This could be something that is not discussed at all...it would certainly tear at trust levels....if there has been no cheating it seems odd that the deck would be stacked so against him?

This is a toughy...diffently talk to someone
