<human>: I've (19M) known this girl (19F) since my senior year of high school and we're both sophomores in college now. We both have had relationships since high school and have moved on. We see each other from time to time, but nothing to big, just a party here or there. She hits me up constantly and always messages me. I've been told by her close friends and family that she is in to me and she never denies it. When we do meet we flirt and go back and forth for a while,but I keep finding myself being distant for no good reason. 

  Despite these signals and signs I still don't ask her out and find reasons not too. Such as "it is a long drive to her house", "right now I'm in school and shouldn't worry about relationships" or "relationships are expensive and I don't wanna waste my money" something not very solid to use a real reason not too. 
  
  I still do get jealous when I see her with other guys and things like that. For example, the other night I was at the club for her cousins birthday and we flirted back and forth, danced a bit, but as time went on I just kept pushing myself away despite wanting to be with her. Then eventually other guys asked her to dance I got jealous but realized it was my fault for not really making that move. I don't know if I'm making the right decision by making these excuses and not going for her or am I just denying myself the opportunity to be with her out of fear or some idiotic reason.

Can you condense the text into three sentences or less?
<bot>: I am pushing myself away from a girl that I've known for a long while, I'm attracted to, is in to me and I have no clue why; or if I'm doing the right thing.
