It was my ex's birthday two weeks ago, a surprise party was thrown for her. Her roommate sent me a text saying she had broken down and cried when she saw I wasn't there and wanted me to come over. She has had a new boyfriend since this summer, they've been together 6 months at this point. They are having trouble and that evening her boyfriend refused to come to the party. I've always been very open with her about still being interested in her and we've been on and off since last year but we hadn't slept together since this summer.

So, I went to the party, she spoke to me, we had a good time, then we went to bed and fooled around, the next day she skipped work and we spent the entire day in bed. A month ago, we talked about getting back together, she told me she loved me and she was conflicted, but when we slept together on her birthday and the next day, she still had a boyfriend.

She is still with her boyfriend now, and I asked her not to contact me for a month if she doesn't want to move on from her boyfriend. AITA for sleeping with my ex while knowing she has a boyfriend?
