PON, GM speaks wisdom there. Of course she's attacking you. Who leaves a perfectly good spouse unless there is something wrong with them? And there's no way she wants there to be something wrong with her, right? That's not how a breakup works my friend.
She will attack more and more. Especially if you defend.
One question for you to answer: are you a good father? I suspect you try very hard and are. If that's the case, there is no reason to defend. Defending only gives her a chance to attack more. Knowing and the silence that comes with it is the better way to deal with that. It starves her of the ammo she is searching for to make herself feel better.
I've been there PON. Believe me when I tell you, reality has nothing to do with it, but being defensive does.
Kind of like her asking you to move out. Why would you? This is what she wants, not you. Next time let her move out.
In the meantime, keep doing what you're doing with the kids. Her attacks say more about her than they do you, and you need to know that.
Peace, AJ
