Hey Mit,
Take a look around the entire Loveshack.org forums. You'll see alot of inquiries about relationships seriously outweight the inquiries of "does he/she like me".
If she likes you, what do you do? Oh man. If we only knew. You asked "how do I find out?" in which I ask only this. Do you
really wanna find out?
Every time I need a reminder of why I'm happy being single, I take a gander around loveshack forums. Every time I need a reminder of why I'm not, I go outside.
Best of luck to you! (oh yeah, I forgot the advice. Just ask her)
