I don't know what I did and I've always thought myself as a nice guy but a few days ago I was told one of the girls from my school needed help with some school work by her friend and she asked me to help her so I said I would help if she asked me directly so I just waited for a reply and the friend came back and passed this on "mmm. he scares me coz makez me feel dumb =["

So I went to ask people what they thought of me (indirectly) and most of them saw me as an elitist, hardass who likes to make fun of people for the lulz, and a liar. A few also thought I was a pretty funny guy.

I like her but I'm not really looking for any sort of relationship because she obviously doesn't like me and she's pretty cute too.

I've known this girl since 2nd grade and I don't think I've never done anything to make her feel this way. If anything I think she's smarter than me and she would even give me a hard time about it during Primary School.

What can I do to change the way she sees me if she won't even give me a chance?
