I do regret filing because I know that is one part that is making any reconciliation impossible right now(besides OW). He throws it in my face every now and then.
This really jumped out at me...when H and I were separated, the one big thing he was too angry to move forward over was that I moved all his stuff out of the house (after we had already decided to separate). My point being: it's an EXCUSE he uses. Please don't let the negativity of regret cloud that truth for you, or allow him to throw it in your face.
