yep as rock said it aint easy tellin someone you like them, however you got 2 choices here.

1. you dont say anything and just stay friends and it tears u up inside (depending how much you really like the person), or she eventually meets someone else (which will happen) and your friendship will eventually grow more distant and go away.

2. you go for it you pansy, and either it works out and you invite me to your weddin a few years from now or she says she doesnt want a relationship. Which then she is either mature and you can still be friends (it is possible folks i have done it) or she is a immature and she acts all weird or starts talkin stuff about you.

I did the short and easy versions here cause who knows if you gonna bother to heed my advice, but ive been there done that so i know what its about. I say go for it, what you got to lose?
