I too get the feeling that he is mad at you about something and punishing you. When I went back and read your original post, he seemed less acrimonious before you were married... or was it before the children? Or is he mad because you pushed for commitment? I'm not saying this is right or justified but I agree that you need to know this.

In a backhanded (!) sort of way, if these recent convos have increased his mbing, that's a good sign that his juices are indeed flowing, so to speak. This type of convo can stir up the libido; it's just that you want him to direct that libido at you. But the fact that he does mb and that he does mb more when riled, could turn out to be a good sign in the long run, IF you can pull the covers off the grudge he seems to be holding.

I mean, there's the part of his personality that has always been quiet and keeps to himself-- okay, that's a given. But some of his behavior does seem-- at least from over here-- to be directed at punishing you. It's like he's saying to you: "I'm NOT going to let you GET to me! I'm NOT going to let myself CARE! You can't MAKE me!" <accompanied by a stomp of the foot!>

Also I think it was good that you said what you said and then left. He'll be thinking about it. If you had stayed and insisted on an answer, he probably would have found some way of turning it against you.
