Motivation after a break-up

My boyfriend broke up with me yesterday because... how did he put it, he finds the majority of other women better looking than me. 

He said he can't help but look for hotter girls when he's with me, and that I'm just boring in comparison to them.  This, obviously hasn't helped my confidence.

You'd think something like this would make me more determined to look good, but we were together for a year and it's completely crushed my confidence. 

Please can someone give me some advice on how to stay on track.

Thanks.

BAH forget him (I know, easier said than done)

Anyways I find I lose weight more efficiently after a break up. For some reason the anger or spite in me makes me work my ass off at the gym and poof there went 10lbs after 2 months haha (with diet too I should mention). It doesn't heal the heart but it sure makes the ego feel better. The rest will come.
