A few months ago I met this girl and developed a crush on her, but that passed away and I just seem to idolize her now. The problem is that me and my friends meet her on a regular basis to hang out, and I see how she makes an effort to be closer to them but not me. She will message or call them, and just do stuff for them and she doesn't make an effort to talk to me. And this really hurts me because I seem to care so much about her and it's not returned. I know I don't have a crush on her now because she likes someone else, and I'm completely OK with that. It's just that I get so jealous that she wants to spend time and be good friends with everyone but me. She is a really good and loving person, which makes this more unbearable that she does this to me. And I can't stop thinking about her, I want to so bad but all I ever think about is her and how she hurts me like this.
I think I know how I could have pushed her away, I sent her a message when I first met her just telling her how cool of a person I think she is (I was really starry eyed when I wrote it) and ever since that I've felt a separation. All I want to be is her friend, and to stop idolizing her and thinking about her. How do I do this? All I do now is try to be aloof and nice when I see her, but it seems to produce no results. All I want is that gap bridged so I can move on with my life...

Just go talk to her and see if you have things in common. You've told her how cool she is, ask for her number, and don't be scared to chase a little, and don't worry about the attentions she gives others, as you're the one trying to see if she has feelings for you, so find out.
