Which?

Okay I just broke up with my boyfriend and I asked for a question about it so if you want to know why then read it. Okay and I heres another question I think this guy is like freakin hot and my friend told me he thinks im hot too. But that friend sorta lies sometimes… So im not sure if he does. I always see this guy but it doesnt seem like he notices me.. And theres this other pretty girl who likes him but has a boyfriend. And every guy like loves her. Should I try to get to know this guy? Or should I just dream about him and back off?
