I have this friend who is just. She is so amazing and cute and nice and I don't even know. The only problem is that she dose not like me back. I'm not exactly attractive... That plus she "doesn't want to ruin a good friendship" so yeah, no chance. But I just can't get over her. I just don't even know what to do.

You find a way to get over her and move on. That's what you do.

She doesn't want to be romantically involved with you. She's apparently made that very clear. You can't make someone love you, no matter how much you think you love them.

If you can't be friends with her because of your feelings, it's best to break off all contact with her, and find a way to move on and meet other people.

I've been there. Sometimes you're friends with someone and for whatever reason, you just can't be more than friends. It's hard but you just kind of have to get past it and stop thinking that way. Just keep in mind that eventually someone will come along that will be available to you. As was already stated, if being friends hurts you too much in knowing that you can't have more, then it's best to just let go and move on.

First it has nothing to do with looks, ugly people get girlfriends, date and marry.

You either be OK with staying friends, or you end any relatoinship. No other real choice

The other posters are right, if you need time to deal with your disappointment, take it by leaving her alone and focus on other things.
