This is killing me, really, really killing me, I can't hold it anymore.

I've been in love with the same girl since October 20th 2009.
I've never crushed on someone worse and what makes it worse is the fact I can't have her.
Because I'm gay and she's not. I love her, I really really do.
And she teases me. She'll curve and roll her body on mine whilst lying on top of me.
She doesn't think she's doing anything wrong, but it kills, it really burns.
She's my best friend so I won't dare just drop her till the feelings go, but every time I see her, I melt inside, I feel happy but I also feel so bad knowing she'll never be mine.

Help, anyone?
Please, it hurts so much.

Phy.

How old are you? (My suggestions will vary depending on age.)

Why do you think you are gay?

Why do you think that this is a friend? This is someone who likes your attention, and is willing to do anything to get it including physically manipulate you, and screw with your feelings? If she is a friend, then telling her to stop her behavior because it is confusing for you shouldn't be an issue. If it is an issue, then you know the truth about your friend.
