1) Have the two of you actually defined "halves" or the respective spousal boundaries in the relationship? Expectations?

I don't even know. No, I don't think so, because I'm not even sure what the question means.

H seems reluctant to take ANY responsibility for the problems, other than to declare himself a hopeless @sshole. We don't discuss or define much of anything. I talk about what I think or what I need and H sits there not saying anything, unless I say something that ticks him off, in which case he'll make a crack about it on his way out to smoke.

We don't seem to agree on anything except that we're both unhappy.

Maybe take the weekend off - no relationship matters addressed.

I plan to do at least that. My head is spinning and I'm not sleeping well.
