Not at all. It seems like the reason you stayed with him for so long was for your kids, not for you. I stopped feeling for Lina a while before we broke up. Mind you, it wasn't 6 years, but it was like a year and a half. Haha.
But! Good for you! I'm happy that you don't miss him.
=D
Well, happy that you are happy and lovin' life.
;D
