AIBU fed up with getting the brunt of DH anger

[Ihaverunoutofideasforaname]

My DMIL is at the end of her life. She has cancer and has for many years now. We knew she was going to leave us some time early this year. For the last few weeks I have been verbally and emotionally battered by my DH. I have a really stressful job and come home to anger and emotional blackmail nightly. I have had shingles as a result and I get eye spasms now because of the stress.
AIBU to say enough and stop taking it out on me, or do I have to take it until the end and beyond?

there's never a good time
and he sounds hideous
and I'm sorry to say I've seen people spend much longer suffering with the cancer than the doctors expected...lots of "it will be a few days now" and then a couple of months later..

before your second post I'd have said it was worth having a chat but you say he's always treated you badly, have I got that right? Is he using his mother's illness as an excuse to make things all about him?
