.I still love the man he was, I know he is not that man anymore.

According to what his friend told you, he never WAS that man.

Make sure you have a clear picture in your head of what he would have to do before you would even consider taking him back. It would be far too easy to take him back if he came apologizing and crying. But it would be a mistake unless he has done the hard work required.

A twelve step program for sex addiction and a year of private therapy for him would be a bare minimum.
