<human>: Hey, I'm not sure if this is the sub to ask but I figured that if I needed some tough love, you would have no problem giving it. I'm sorry if this isn't anything as serious as some of the posts here but this is really Messing with me.

So the situation goes like this. I met a girl in some unusual circunstances about a year ago and I worked up the courage to say something to her. The first time we really hit it off, or so I thought, she was really nice and seemed interested to get to know me. Please, bear in mind that I never asked her out.

Time goes on, whenever I see her I either freeze in my tracks and don't say anything of I suck it up and to to her. Even though she's never the one to come to me, she's pretty nice. Eventually I ask her for her facebook and she gave it to me but via FB she is not nice at all, she either replies in a very curt way or she doesnt say anything at all.

This brings us to last week, we've spoken a couple times and it went fairly well but last time I was with a classmate so, even though we saw each other, I was unable to say anything to her, except for when we were hopping off the train and so was she. I said hi to her and, barely looking my way, she says "hi...bye" and storms off. I understand that she could have been in a hurry but she was just so curt.

Well, giving her ways, I asked her on fb if something had happened and if I had somehow displeased her she basically said "lol were did that come from, I had a bus to catch as usual" and didn't say anything else not even when I apologized, but I can't shake the feeling that something is up.

Well, this was all to give context and I understand if this is not the place to ask but I really don't want to make the girl unconfortable and if you thought that you,in this situation, would like to be left alone and i should just back off?

Summarize the given text in a few sentences.
<bot>: I met a girl I'm really interested in and, given my interactions with her and my overall por social skills, do you think I should back off?
