<human>: Give me a shortened version of the text

I met this girl a while ago and from the first day of college I started talking to her because she was cute and I was trying to branch out. After hanging out all day and even allowing me to buy her lunch she at the very end of the day just tells me she has a boyfriend that's in the armed forces which I'm not too concerned with I just decide to give her a little space. We were still friends and I walked with her to and from classes and just engaged in small talk but I tried to seem as little interested as possible. (if I had a gf, I wouln't want guy talking to her so I tried to give the other guy the same treatment.) Yet she still talked to me and walked to and from classes like normal.

This would be ok normally, it's nice to have friends in a new place, but things lately have gotten weird. Now she will text me 3-4 times a day and always wants to hang out and when we do hang out she seems really flirty (always complimenting the way I dress, when we study together she sits really close to me etc.) Usually I will make up and excuse and say that I'm not at campus but now she texts me in between classes and still wants to hang out and has asked me before to come to her room and hang out alone, which I only did once but I got out of there quickly. Besides past girlfriends that I've had I've never met anyone who wants to hang out that much so I'm getting massively confused by this behavior.

On top of all that she has told me she really cares about her boyfriend and how they've been dating for a while.
<bot>: Girl with a boyfriend is making me feel weird. I don't want her to cheat and rather her leave me alone and stop being so flirty.
