My girlfriend broke up with me about 2 weeks ago. I've given her space, no calls or emails. We go to the same gym and when we see each other I always smile, say hi and leave it at that. Last night, I saw her at the bar and again, smile and hello. She was with a group of friends and so was I. I work with a lot of women so I was in a crowd of about 4 women and one other guy. She knew where I was standing and her group of friends stood close and my friends, her friends, her and I were looking at each other a lot. I was acting cool and joking/talking but it was killing me inside seeing her. She started talking to this guy who didn't really look her type and then they danced and then I could see him putting her number in his cell. This was killing me but I played, or tried to play cool. My friends were telling me she keeps looking over here. They told me to stop looking at her too. Finally a friend of mine called her over and she put her hands on my waist. I told her I hoped she would have a good night, that she looked beautiful (she did) and she kept looking at me sad. I told her I was giving her space but had things to say. We were getting kicked out of the bar (closing time). She was almost in tears and told me she knew this was breaking my heart. I told her I didn't want to make her uncomfortable and she left with her girlfriend. Should I call and aplogize? Was she trying to make me jealous or really moving on?
