So my boyfriend and I broke up 2 months ago (he broke up with me). But we had the same group of friends so we agreed we would try and get through the awkwardness and work to rebuild a friendship with each other. It was going really well recently we are able to hang out and chill and joke and I haven’t got upset about anything in a while. Now obviously he was over the relationship a while because he was the one that broke it off. He has started having a ”thing” with one of my really good friends in our group. I feel so hurt and angry and upset that he would do this. But i want him to be happy, do i have any right to feel angry at him? I feel if ”thing” goes much further being friends wont be an option it hurts. I just dont know how i should feel or deal with this.
