Do you have another explaination?

I was at pub/club/bar with a group of friends/acquaintances. There I grinded with a lot of girls most of whom I knew. My dancing was pretty random except I was focusing on this one chick trying to spend longer amounts of time with her . I spent about 50% of my time with her, mostly dancing. I thought that she liked me before we ever went to the club. Our faces got very close multiple times and I tried to make sure our lips touched while talking and dancing. I never kissed her and certainly did not want to make out in public (like a drunken couple). Everything was going great from my perspective. She would look over at me if I was talking with someone else. She had no problems holding my hands while dancing.

So I did what any reasonable man would do, I asked her to leave. She said no and I though she wanted to dance more. But as the night got late, she kept saying no even when she said she was tired (I probably asked 3 - 5 times over 3 hours). She could have left me at any time with only slight resistance. I was getting annoyed with her. We ended up leaving with several other people; she didnt walk next to me, I didn't want to be clingy and accepted my fate for the night.

I would not change a single action from the night except I might have kissed her once. I only have a slight theory and I wonder if you have any others. She was very drunk that night and may have been nervous about doing something she would regret. I do not think she has been very sexually active and perhaps I gave off the vibe that I was pushing her towards sex. She did tell her/my friends that she would make out with me early in the night. I think that there is a very small chance that she didnt know I wanted her b/c of the dancing with other girls. I was drunk but certainly much less so than was she.

Do you think it is time to just forget about her or should I give her a little bit longer to warm up? I tend to want to give her another chance b/c I like her, but perhaps we just dont match-up. I will see her many more times with my friends, the only time we could really be alone would be if I could get her to leave on a night that we partied somewhere. I really do like her as a person but I am not going to put up with that behavior for much longer b/c I could spend my nights talking to other girls that are interested in me.

Just curious if anyone has any insight into why she acted this way.
