I'm self described as schizoid personality andt thus far from an expert on relationships, but maybe I can give you something from my history.

I'm a 31 year old male who's never had a relationship last more than 5 dates...roughly three weeks. I'm old enough now to realize I'll never get married and that's probably a good thing. Not to say I don't still meet girls I'd love to be with, I just don't have the ability to form close relationships.

You've dated 5 girls in 2 years at 1 date apiece, which is pretty close to what I did at your age. That's not a very active social life. You don't give any reason for this in your post, so I'll assume it's normal for you.

Regarding the girl you're crushing on, it's perfectly normal to feel that way. Her having a boyfriend dosn't mean she's married. But by agreeing to keep your distance in school means you've already conceeded defeat. Eventually the school year will end, your interaction with her will decline and you'll get on with your life. Your only chance would be to do things outside school with her, such as shopping at the mall or seeing a movie. Without that, you're just friends.

Your last paragraph is a bit confusing. Nobody 'deserves' a girlfriend no matter how admirable their personal qualities are. You have to earn that right through your interactions with her. The guys who get the girls you want still have to work at it. They may have a lot more natural talent such that it dosn't seem like they're working that hard, but nothing in this game is easy.

I'm still amazed when two people I know fall in love. I can watch the whole thing develop over weeks from the outside looking in, but it's hard to comprehend. Physical attraction is important, but I think it mostly comes down to two people being comfortable around each other, making each other laugh, and most importantly having the ability to share parts of themselves emotionally with each other. That last part is where I'll always fail, so that makes it most important to me.

I was 23 years old once, and before that I was 16. You can gain perspective with age, but you never outgrow problems such as this. Realize that every 3-6 months you'll meet another girl you have a crush on. Be prepared to make a legitimate pass at her, go on a date if you can. Don't be supprised if you fail. Endure the pain and loss. Then try again with the next girl who catches your eye.

I consider that my failure. That I was never willing to accept the pain of failure in exchange for a chance at a relationship. I've been told it gets easier with practice, but you'll have to find out for yourself since I'm not going to.
