Ugh, that sucks mama, I am so sorry.
I remember when my little guy (now 2) was born, and my husband didn't help me at all. He was working a crazy work schedule, but he'd sleep all day on the weekends and seemed to simpy just NOT CARE how I was doing or how the babe was doing. It's like it was all about him, his sleep, his state of mind, and his annoyance that laundry wasn't done, etc. He was like, "you're home all day on maternity leave (I was working at the time), what do you do all day?"
I just kept quiet and let the resentment build, until finally, when babe was about 4-5 months old I completely lost it on him, to the point where I told him to get the hell out. That seemed to snap him out of it. I hope you don't have to wait that long for him to get a damn clue. Seriously, I think they are just DUMB. My dh is also not at all caring when it comes to my pregnancy, he never asks how I'm feeling or if I need anything. I've come to just let it go (since fortunately I have easy pregnancies, so I don't really need much), bu luckily he's much more helpful and supportive with our little guy now, and I expect him to be helpful and *caring* when this new guy shows up.
Anyway, be well, and BE STRONG! Stand up for you. *hug*
