My ex gf broke up with me March 28th. Four weeks later she told me she slept with my now, EX-best friend. I know it's nice and legal but it still hurt a lot and I felt betrayed. I went no contact and went back to live 9 hours away for Summer school. I'm gonna come back at the end of the summer to see my family and because of our close nit group of friends I'm sure she'll see me and want to see me (she didn't want no contact she wanted to be friends HA).
My question is: What do I express to her when she contacts me in person when I go back home? What do I say to him? I'm civil, I don't want a fight or any trouble. I still love her to death and of course want her back in my lowest moments (at my highest I'm ready to move on) but I feel like a sap being her friend while she's continuing to romantically see my friend (even though they're not dating). She sees everything as legal but I see it as a kind of betrayal, especially after 3 years of a near perfect relationship. Am I right to feel betrayed? Am I justified to think they shouldn't expect me to want to be friends with them?
I've heard everything from "what a bitch" to "she's human". I need to hear the truth.
Thanks everyone.
