I work at a bar, and a guy I'm about to go on a date with tomorrow, offered to come visit me with a friend of his. Meanwhile, a close girlfriend of mine came as well (separately) to get a few drinks. I was very busy taking orders and bringing people their drinks. So, as my girlfriend walked in, I hugged her and introduced her to my two friends (including the guy I'm going on a date with). Anyway, fast forward. As I'm running around taking orders, I notice my date talking a lot to my friend. He even switched seats with his friend to sit next to her. I kept bringing them drink throughout the night, until my other guy friend decided to leave, leaving my date and my friend alone. They chatted for a while, and then decided to grab late dinner together. They both said bye, then my date came over and asked me how much he owed me and I said nothing it was on me. Then he said thanks and left with my friend. (In all fairness, I said it and walked away, but still... )

Now... part of me feels like, well he's not exclusive to me anyway. We haven't even gone on a single date. We did hook up during New Years, but that was it. This is a guy I've known for a while by the way. We're not close friends but have known of each other for a while, we went to the same elementary school up until middle school. He left but then stayed in the same group of friends so I would see him pretty often. About a year and a half ago he asked me out, but my close friend didn't want me dating him because she and him would hook up every so often and she didn't want me to jeopardize that. I completely understood and avoided dating with him for a year. Throughout that whole year however, he continued to pursue me pretty hard on. Until we finally drunkenly hooked up on New Year (my friend is now leaving out of state permanently and has no problem about it, just FYI!) He has always been very respectful to me, and even said on New Years that he had been waiting to kiss me for a very long time.

So, here's my problem... Am I over-analyzing? Is it completely okay for him to chat with my friend at the bar and leave with her for dinner? Or was it disrespectful of him? I somehow feel hurt by it. I know he isn't tied to me, but watching it happen before my eyes knowing I'm supposed to go on a date with him the next day, kind of makes me feel like a side dish. I don't know how else to explain it. I wasn't looking for anything serious in the first place (He's leaving in a few days to work out of state for a year). But I don't like to feel disrespected nonetheless. Just reaching out and hoping to get your opinion on this one. Should I still go on the date with him, or was he completely rude for doing what he did..

Ps. My girlfriend later texted me saying that she and him had dinner and it was 'completely platonic' and she just wanted me to know... on that note, he never texted me anything.
