Here's my problem:

I go to high school and i have been practically in love with this girl for 5 years.
The first 2-3 years of school i was really shy towards women and was an idiot when it came to women.I have opened up alot over the past 2 years and when i look back i think she was trying to get my attention and that she did like me.

I don't know if she still does,sometimes i think she is looking at me but i don't know.I think she is the most beautiful women i have ever seen. I get goose bumps looking at her, constantly thinking and looking at her.Its driving me crazy. I don't know what to do.I find it hard to talk to here because she is so amazing and when are eyes meet its like my heart jumps out of my chest.

Were not really friends but friendly towards each other we hang out with different people.

Basically how do i know if she likes me and how do i ask her out.

Any help would be much appreciated. Thanks

Please Help
