Input: Okay so this is kind of complicated. I'll try to summarize best I can.

My friend and I were in a short relationship, and we weren't that obvious about it, so I don't even think our other friends really knew. It wasn't a very serious relationship. One day he has this heart-to-heart with me and it results in us breaking up amicably. We're still really good friends.

The thing is that he probably thought the break up was mutual because he kind of hinted that he would stay with me if I asked, but I acted like I was fine and sort of encouraged the break up because I knew he wasn't really into it anymore. But actually I was crushed and didn't want to break up; I just didn't want him to feel bad because he's been really good to me.

Anyway so like a month later I find out he has just started dating one of our mutual friends. I thought I'd be fine with it but I wasn't. I had prepared myself for him to get with others, but I think I was just messed up over it because it was this specific friend I was insecure about when we were together. He always seemed to favor her, and I even sort of asked one time if he was interested in her. He assured me he wasn't, so the fact that he ended up dating her anyway just made me damn insecure. I want to tell myself that he just happened to change his mind in the time we broke up, but I can't help wondering if he had wanted to be with her all along and felt trapped by me.

Anyway I don't hate that mutual friend or anything, she doesn't know about the whole thing and she's a super great friend. I'm actually really happy for her. They're really good together. Better than I ever was with him, which is kind of bittersweet for me.

I didn't want to tell him I was sad, but honestly when I found out (she had casually mentioned it to me), I burst out crying. I thought I should tell him, since it felt like something I shouldn't hide, so I did.

But now I sort of regret it and wonder if it would have been better if I had just kept it to myself. It's not his job to make me accept his new relationship, and I know he feels super shitty after I told him. I feel like an asshole for stressing him out over this.

telling my friend (also ex) I'm uncomfortable with his new relationship
