Thanks everyone, but i'm not sure that issue was the reason though, i'm just not sure if it played into it or just gave her the wrong idea. It's not that I didn't want to, I just didn't at the moment. Still, she seemed to have took it wrong and I should've talked to her about it.
I think it may have been because I became a different person around her. I was more reserved and afraid to express simple things like my sense of humor because I didn't want her to think less of me. Crazy as it sounds, it wasn't that I held back intentionally, it was just a nagging instinct to become somewhat reserved with my actions and what I said. I don't even know i'm doing it sometimes and I certainly don't mean to, but it's been persistent throughout my life around someone i'm interested in. Ironically enough, that's probably what steered her away. Plus that, she was probably sending many signals I didn't pick up on. I've been getting better and trusting instinct more, but it still happens.
Even so, it's been about three weeks since we last saw one another and at least two since we last spoken so it's really too late to tell her how I feel without sounding crazy, it's just I felt bad for letting things end on such a bad note.
