Is this wrong what he did?

Okay my male friend and I have been friends for almost two years. At one point in time we were trying to date but it didn't work out so now we are friends. During the time we were trying to date I did something that really hurt his feelings, and I admit...

I was wrong. I've apoligized to him over and over again and I've been trying to make it right. If I'm wrong I have no problem admitting to it. Anyways he has other female friends and he told one of them about what I done to him. One night when we were talking he told me he discussed it with her and he felt a lot better. I felt that was wrong of him to discuss that behind my back because that's between us. I felt like he was talking about me. When I asked him what his female friend said about the situation he wouldn't tell me. I would never talk about him to one of my other male friends if he did something to me because I know they would say something negative. That's what I feel like was said about me. He should have discussed this me not her. I feel disrespected. For that reason we have not been talking. I don't think I want to be friends with him anymore. What should I do?

It wasn't really long.. it wasn't like he was saying Oh my god I can't believe she did that, what a b*tch, he was just trying to get advice from a friend.
There's a difference between talking about someone behind their back to get advice and talking sh*t about them behind their back.

some times people need to get things off their chest.. you cant tell the person that it happened with.. sometimes you just gotta tell someone else
