I'm really bitter towards my ex's girlfriend, how should I deal with it?

I think that she can understand where you're coming from. No one wants to be "buddies" with someone who destroyed a past relationship and caused them pain. Two things that she did, and you retaliated the same way anyone else would have. In anger. The best you can do now, is tell her that you want to bury this hatch and move forward with her, just the same as you've moved forward in your love life with another person. She might say no, but if she says yes, you can go on to show her that you meant what you said by being open in your group sessions but also ask for her forgiveness. I wish you the best! Good luck
