OK, I also just want to work out if I got things right the way I saw it. Can someone maybe explain what it means when she did/does the following things:

1. Before she knew me, she smiled at me and insisted on greeting me. Let's say she sat in front of me in another row of seats. She would then keep looking around until she caught my eyes and then she would smile and say hello.

2. Once she knew me well, she would randomly begin telling me stuff that happened in her life and it's stuff I know she wouldn't tell someone else, because some of it was really private and not something that would make you look cool.

3. There was a two week period in about August 2011 where she seemed really friendly with me and touched me on the arms regularly, and this one Friday night I had to stay behind to do some work in the laboratory, and guess who decided right there and then to stay behind also and do some lab-work that evening? I also touched her many times afterwards and she seemed to like it/was OK with it.

You see, I was listening to the other people in my class who were saying the whole time that she and that other guy were going out. Maybe she wasn't really into that guy and was trying a last effort (August 2011) just to see if she could connect with me, a guy that she maybe liked all along. They had a really short relationship in 2012 and she broke up with him, from what I heard. I thought she was off-limits and so I backed-off. Maybe I should've "stolen" her away. I'm just not that kind of guy, I would never do something like that, but now it looks like I should've. That other guy clearly just messed with her, thinking back he was a real player and cocky guy, ungentlemanly and the sort of guy that just messes with girls, no matter who they are. Maybe by the time I contacted her, she was so over all of it, she just didn't want to know about it anymore.
