wow... i know we've just met, and so who am i to say anything... but wow, that's just so wrong an insane...
i don't want to sound cliche, so i'm not gonna tell you to just forget him, move up, and cheer up. i can't say i know exactly what that feels like, but i know what it feels like to hurt also, and that kind of thing takes time to heal from. i hope you're doing better, even a little better by now...
trust that everything happens for a reason, good and bad. and also it's not the end of the world. life goes on, you have no choice to to move forward with it. also, it's always good to focus on what you DO have, rather than what you DON'T have.
wish you luck, hang in there, 'kay? :)
