I'm sorry you're not in such a good place
I think some people are inherently more caring / nurturing when people are in need, and they have almost a built in instinct to care and protect.
I personally have a need to feel nurtured, or at least comforted when I'm upset by my partner. Not in a bad way I don't think. Just in a way when I'm having a crappy day it's nice to speak to him about it. So when you don't have that connection, that's a really difficult thing.
I was wondering what your communication is like with your husband in general. Not just when times are tough. Does he listen, as in really listen, when you speak to him?
