I agree with Becky, sometimes it's hard to see the big picture but losing a perspective on life because of a guy is just not worth it... It might seem like you're in a dead end now, but believe me, life goes on, and time is a great healer, as cliched as it sounds. There are always times in your life when everything seems pointless, but out of experience, I can say that it does get better... Much better!

If your ex is obsessed with your best friend, he probably isn't someone you thought he'd be, and certainly not someone you want to be with... And it hurts to be dumped, but don't lose your perspective on life, and don't feel worthless just because of one guy.
