<human>: Summarize the given text in a few sentences.

So I will try to cover all the important points and keep this as short as possible. So last semester I had a class with this girl who I thought is really cute. One day she happened to sit next to me and ask me a question about how to get tickets for the football game for our school. After that almost every day before class we would talk, and even a little during and a little after. When we did talk there was a lot of eye contact and laughing and on a few occasions she broke the "touch barrier".

Now I also found out last semester she had a boyfriend by overhearing her talking to one of her "friends" in class about going to see him, sincr he goes to scool out of town. (I say "friend" because she would always kinda bitch about her to me.)

This semester we are both taking the same follow-up class but at different times because of how our classes worked out. So I figured I'd probably never see her again, so I went ahead and sent her a friend request on Facebook last week and she accepted it. However a few days ago when I'm leaving this class I'm walking down the hall and I hear someone say my name so I turn and look and there she is sitting on a bench. We ended up talking for about a half an hour and once again there's a lot of laughing and eye contact, but once again I chicken out and never ask for her number. While we were talking she happened to remember things we've talked about last semester, like jobs, classes and etc. When we were done talking I had to run off to my other class so we say our goodbyes and I start walking away and she says "it was good seeing you again" and I say something similar back and just continue walking.

Now I am concerned a little because of a few reasons. There's a good chance I never see her again. I'm worried she was just being nice and not flirting with me. She's still never brought up her boyfriend to me and I feel like I should assume she still has a boyfriend. I also wouldn't want to be a "home-wrecker" if they were still dating.
<bot>: me and a girl used to talk last semester quite a bit, but I'm unsure if she just being nice or being flirty, and there is a chance she has a boyfriend.
