how long do you do no contact?

[MrBond]

Those aren't concrete reasons. Sure you have shared history, etc. But everything you mentioned is out of obligation, not attraction.

What is it that would make you attractive to him?

Things like the healthy lifestyle is purely subjective. You might have thought it was healthy and he was just following along to make you happy. YOu said you condemned him for the porn, heavy metal, Howard Stern, etc. But maybe those were things he enjoyed. It doesn't make him a bad person. How tolerant were you?

Again, what makes YOU attractive (looks, career, personality)? Try and give specifics and not generalities.
