I'm sorry you're going through this. I know what you're going through. My dad cheated on my step-mom (after being together for over 10 years) with this woman and now THEYRE MARRIED. I didn't go to their wedding and I barely acknowledge her when she's around. Also, she was cheating on her husband with my dad so it was definitely messed up.

I totally understand how you could hate him right now. But I think it's misplaced anger. My T helped me work through it and helped me realize that i wasn't really mad at her, I was mad at my dad for being such an ***. But I need that relationship with my dad so I put my anger on her. Granted, even after I got to know her she was still a total *****, but I finally got over putting my anger with him onto her. I hated feeling like I have been cheated on and the one guy I should be able to look up to is just like the rest of them.

I hope you feel better and feel free to PM me.
