I'm trying to convince myself it's just because she's really responsible, but I'm pretty confused to be honest. She obviously knew I was intending sex when I asked her over and asked if she wanted tea (ie an excuse to stick around) but then it was like she changed her mind. And it's not my kissing, I'm pretty sure my kissing is fantastic. So no, I didn't really have much of a chance to go further. I was rubbing her back while we were at the bar and I had my arm around her while we were walking, but nothing much.
And I've told her that I like her and find her irresistible, etc.. so.. I don't know. I was literally 95% sure I was getting some last night and suddenly it changed. I know she's not good with less sleep and school is her #1 priority, and if she had stayed she would have been looking at 4 hours of sleep at best so I'm not upset about it.
And she was more physical this time. She kept putting her head on my shoulder and would touch me when I was joking. Still was fairly reserved, though. So.. I dunno. I dunnnnno.
