My boyfriend and I have been dating almost a year, and have gotten along pretty well until now. We have a LDR during to me being in college and he's working in a different college town. 

Anyway the problems all started last night. We were texting and I casually asked him what he was doing that night since I knew he wasn't working. He told me he was going bowling with a girl he knew from high school named Sarah. I normally don't have any problem with him hanging out with other girls, I'm use to it since he lives with two girls anyway. He told me that they were going to go drink and bowl at the local bowling alley (where he works). This just seemed too much like a date. I have no problems with them hanging out, but the bowling plus the alcohol it just seemed a bit sketchy to me. 

Anyway I told him I didn't really like that idea, and I said that a group thing might be better. He promised that it wouldn't happen again and I went to bed. I woke the next morning and we talked for a little bit, turns out he went and did it anyway despite me being uncomfortable with it. I'm really annoyed with this because if he'd ever told me he wasn't uncomfortable with something I would respect his wishes and I wouldn't do it. I even asked him how he would feel about me going out with a guy he didn't know in the same situation he's in. He agreed that he wouldn't like it at all. Am I overreacting or should I be concerned?

For the record I don't know Sarah at all. He introduced us once at a wedding but I never got the chance to really get to know her, which is ridiculous since she just lived a few doors down from him at the time. I just don't get a good vibe from her since he barely spoke to her when I was around even though they hung out all the time. And one time they were hanging out and he told me through text "I'm hanging out with Sarah and her friends, I'll talk to you later."
