MM - have you up til now been the strong one emotionally-speaking? Has your DH generally relied on you to be strong in this way? Maybe he is finding your vulnerability difficult to cope with (no excuse, but...), and can't process this situation, IYSWIM. What would you like him to say or do? Could you write it down - for yourself at least, even if you don't give it to him?
Is his present behaviour or attitude a surprise to you? Or is it typical? I mean, I get irritated or frustrated with DH at times, but I know him so well, and all his "faults", so things he does never surprise me - they may still irritate me, but not for long as I knew what I was getting when I married him.
I hope you get some sleep.
Gosh, I'm quite tired actually. We have not adapted well to the clocks going back. Sigh.
