Ringing, when you say you haven't the strength to do anything different, what do you mean? Do you mean leaving him? I don't think that's true you see. I don't think you want to leave him, because you still love him. All the other reasons you are giving for staying can be countered, you see. The biggest myth is that the children are going to happier if you stay together. Children are happiest with parents who love and respect each other, closely followed by parents who respect each other, but who live apart and are happy for so doing. Children actually hate growing up in atmospheres where there is tension, conflict and contempt.
They aren't just learning life lessons from your H you know. They are also learning from you. It might not be as straightforward a lesson as Dittany suggests. They might also be learning that adults resolve conflict in the way you and your husband do - and some unedifying messages about "form" being more important than "substance."
Or is it that you can't have a "different" conversation, along the lines I've suggested, about "How did we lose each other so much and what can we do about it?"
Why is that? You DO need to change the conversation, to focus on what's really going on here. If you don't think he will participate in a conversation like that without a neutral person to help, what about suggesting counselling?
Please answer this Ringing. How do you think his emotional and intimate needs are being met? If you don't know, would it be so terrible to ask him?
You see, I don't have the same take on this as others. I don't see this as abuse in one direction only. FWIW, your comment to your friends about the white wine glasses was of course a jibe about his meanness - directed at him, if not them.
I see this as two people who have lost sight of what's really important in a marriage. Who communicate terribly, who hurt each other in different ways. You might lack the strength and indeed the desire to leave the marriage, but you surely don't lack the strength to have a different conversation, or you wouldn't have taken the brave step of asking for help.
