Maybe it was actually your S being there, OM seeing firsthand how he was hurting a child, that caused him to flip.
Again, we all want what's best for you and for every M here. This could very well work out in your favor. But if OM2 or OM1.2 starts, just be aware that violence is almost certainly the wrong path at that point. If she's impressed by it, it will be the first time. If she rejects you again, it's time to go dark or file.
And yes, it is possible to go dark with children. Write up a legal agreement for childcare, have all necessary communication through an intermediary, and one of you move out (preferably the wayward spouse).
Best of luck, dawgy! You were the first story I read on here back in July and it gave me hope. On that day you were full of self confidence that you would be okay regardless. I truly wish you the best.
