Can't stand the ideaof ex ending up with woman he was sneaking around with. How to get over this?

After all his BS, you can't let it go?! Are you serious??? You should be extremely THANKFUL......that she took the loser off your hands! You want HIM around for your son's role model? You have EVERY reason to feel good about yourself! You're minus his anchor A$$.....You take care of YOU and your baby.......He lost a good thing in you! Look how $screwed up HER life is!!!...... ^�^
