So a little background story: a while ago my boyfriend cheated on me when we were in a rough patch in our relationship. Long story short, we have moved past this- he has cleaned up his act completely and our relationship is in a much better place now.

So recently we were both invited to a good friends birthday dinner/going out after. Then, I find out the girl he cheated with will be there. (She is completely psychotic btw- when the cheating was happening she would talk shit about me, ask my boyfriend why I didn’t like her, and a lot of other things). She is such a bitch and I don’t know what to do!

We are going to the dinner so obviously I’m not going to make a scene at my friends party- but ugh. What should I do? (I don’t have any concerns about my boyfriend being around her, since I will be there and we have moved on from this) but I just don’t know what to do when I’m around her
