Hi, yeah I completely agree with the above. It can be real easy to get sucked back in, start wondering "what if'"s and downplaying the rest. Just keep remembering why you don't want to be with him any more.
You've broke free so just focus on making the most of that freedom, and what he's thinking, what he's doing now is kind of immaterial. He made his choices now it's time for you to make yours: and one's that are going to lead to you being happier.
