So where to from here, how can i start to repair the damage?
If you were drunk and out of control angry one night and you did something regrettable like shout at your W or throw something at her, and you realized you messed up...would you chase after her and corner her and apologize? Or would you give her some space, sober up, and let the situation deescalate?
That's what you do. The best way to repair the damage is not doing any more. Give her some space. Don't do anything. Anything you do is going to make it worse. Just focus on 'sobering up' and becoming the man you want to be. I suggested rereading your posts with a new perspective and reporting back to us what stood out. The situation will deescalate. Not necessarily that it won't move towards divorce...but with time, IF you become the man you want to be, and your actions align with this consistently, the situation will calm down. When you're in a hole, quit digging.
