damn dude-- that sucks. As was said above...love can be a bitch. I'll tell you this much though...if you think she's the one, don't give up...it may just take her a little longer to realize it- that doesn't mean she's a bad person or that she did you wrong- it could just means she wasn't ready or didn't realize.
However, if you're sure she isn't the one and you're in the situation of moving on-- I wish you a swift and speedy appearance back on the market.
hahahaa, skip to the end
