Slept with my ex's friend
Me and my boyfriend broke up a little over a month ago. I started dating him when I was 19 and we were together for about 2 years. He was my first for a lot of things. But I wasn't his first in pretty much anything (which bothered me a lot, but I ignored it and moved on). So like I said, we broke up about a month ago. I was sure we were never getting back together. He told me there wasn't a chance for us anymore, that he just wanted to be friends. He was even already talking to some other girl. Of course being my first break up, I was devastated. I went to a mutual friend of ours and without even thinking, I slept with him. I regret it deeply!! And I even stopped almost as soon as it started! But the deed was done and I just moved on. Well, recently my ex boyfriend and I started talking again. I told myself I would never tell him about me sleeping with our mutual friend unless he asked. Well one night he asked, so I told him. He was soooo upset! And I can understand why (since apparently he still had feelings for me). He has "forgiven" me for it. But I don't know if I broke some kind of code or something. When we broke up we told each other we wouldn't mess with mutual friends, but it just happened. Was I wrong? I regret the whole thing, but I just feel like I did something taboo. Was it wrong of me to sleep with a mutual friend after my ex broke up with me? Should I feel guilty? I can understand that it was a wrong thing to do if I thought we were going to get back together, but I was 100% certain that we weren't going to get back together ever! So was I wrong?
