My H has also been adament about not having kids the last 1 1/2 yrs. He always wanted 3 before that. I think it's a symptom of the problems in the M rather than a belief change - i.e. they don't feel stable enough in the R to make that commitment anymore.
If your H is anything like my H, he didn't say anything because there wasn't anything you could do about it, so he withdrew to work through his own emotions, thus not providing you any support. He probably also hasn't really come to terms with a lot of that - he's probably been avoiding it.
While he brought up living together, neither of us has any idea what he's thinking now. Also, you have no idea what he thinks you are going to say. He may be thinking you are going to say no or tell him not to bother because you are going to file for D. Guys do tend to freak out when they know we want to talk about the R and predict the worst. Hell, I do it too when my H wants to talk after this last year.
