They broke up in the middle of last year, it was kind of a weird relationship. He never loved her and was never affectionate with her or anything. Anyway, fast forward to last night and we were out for a friends birthday and I ended up sleeping with her. Today is obviously consequences day. He's a pretty laid back guy and will most likely be more ok with it than your average person, but you also never really know where you are with him. I just called him and told him about it, thought he had to hear it from me really. He seemed cool, but fuck was it an awkward conversation. Gonna be a bit weird next time I see him. He seemed more concerned with how she saw it so I just text her to make sure she knows it was a one time thing. Feel a bit douchey.
