<human>: So this girl on the floor below mine in our dorm, both of us are 18 I'm a guy, is (not to objectify, but this is true) pretty much the ideal girl for me. Not only is she smart, funny, clever, nerdy (in a good way) sweet, and very pretty, but from when we first met we clicked immediately and have been close friends since the first or second day that we met, and I'd be willing to call her my best girl friend. 

The only issue is that she's in a relationship with a guy from another university (He is 18 and they've been dating for three years, though they broke up once for a few months). Now last night we were hanging out in my room, nothing unusual she was studying for calc and I was laying on my bed and we were making idle chitchat, then her boyfriend came up. She was telling me about her relationship and I told her my honest opinion that I think that she should break up with him, but I did tell her my feelings on her relationship as a friend not as someone romantically interested. 

Now before I go on I should mention that our interactions recently have gotten more and more flirtatious and everyone is noticing. However when we're alone and talking she responds to everything I say with things that can go two ways, either "I like you" or "I don't like you that way".

What I'm worried about is that if she does like me (our friends keep telling me she does) did I fuck everything up (both her relationship and ours) by saying that she should break up with him, and if they do break up should I pursue a relationship if she is open to one? I'm just worried that she doesn't have true feelings and that she's just looking for someone out of hurt and that if anything happens after a few weeks or months she'll realize I'm not what she wants and then I won't have her at all...

<bot>: I like a girl on the floor below mine, told her she should break up with her boyfriend of three years because it's not a healthy relationship, may have screwed everyone involved over
