Diagnosed a few years ago as a result of previously buried significant childhood trauma. He is currently seeing an experienced psychologist, with slow but definite progress.
Most of the time it is fine, sometimes life is good, but sometimes living with him can feel like hell. I try so hard to look past the negative, grumpy, critical person he can be, as he is also such a good, loving person and I hold onto hope that therapy will set that person free. He is just so broken.
But a lot of the time I can do nothing right in his eyes, he doesn't notice all the things I say, do (and don't say) to try to accommodate his healing. One minor transgression on my part will send him spiraling into a dark hole and he re-experiences his trauma with minimal trigger. I really try to be a good support to him but I am only human and disagreements are part of life (though I've smelted them down to a tiny amount as it makes both our lives).
I suppose I just want to hear from other people who may have been through similar, and any practical advice they might have for getting through this. I appreciate some people's advice will simply be to leave him, and I can understand that, but that isn't something I'm going to do.
