nd_n8, I think it’s incredible what you have done to try to make this situation better for yourself and your family. The strength you and your wife have shown throughout all of this is very admirable.
I can only tell you my initial impression of these events. If the reason your other two kids are not permitted over at your house without their older brother is because of your violence in May, then perhaps your wife is angry at you for acting in such a way so as to put her and her children in this position.
Maybe she knows that you were going through a lot of stress, and acknowledges how hard you have worked in your nonviolence classes, and truly loves you and knows you are a good man and trying to do the right thing… but underneath it all, is still angry, because your actions have led to this situation where she has to both honor your needs as a father and protect her daughter at the same time.
I know, if this had happened to my daughter, that kid wouldn’t be coming within a mile of her ever again – but I can appreciate that the situation is complicated when you love both kids with all of your heart. She has to find a way to both protect her daughter and ensure your needs as a father are being met.
I’m just saying, I would probably be righteously pissed at you but not want to make anything of it because of my knowledge of how well-meaning you are, which might result in this endless loop of talking about it, in hopes that the issue might somehow magically surface. It wouldn’t have to be a conscious thing.
I agree that there may need to be a no-holds barred argument here, as long as you’re certain you could do that without resorting to violence. There is so much that needs to be put out on the table, and no amount of endlessly calm conversation is going to fix this. I can’t imagine how this issue can be dealt with without some degree of turbulence and tension – you both have feelings, go express the hell out them!
I do want to reiterate that I think you are doing an awesome job dealing with all of this stress. But there are some issues for which a self-help style approach is utterly useless. You and your wife need to be aware of what stakes you have in this situation and how much you care about each other, the children, and your future together. Sometimes the only way to do that is to just let it all come out.
