taking care of a baby by myself..

My significant other is the bread winner and I stay at home with the 3 week old baby. I change the baby, feed the baby, stay up for what feels like ALL night with her, bathe her, pick out her clothes, etc. He works from 3pm-12am and when he is home I have no help unless he's asked, and even that can be tricky as he will occasionally find an excuse to get out of it. It even got to the point that I was so tired with the baby in my lap that I dozed off and she nearly fell out of my lap! All while he was next to me on his phone. I've called him out on it a few times but when I do his feelings really get hurt and he's even cried because he felt like a bad father to her and his son. He says he's so overwhelmed and he doesn't have much time to spend time with her but when he's home from work he's either doing something else or napping... my baby is my 24 hour job and sometimes it feels nice to have a break. It also really warms my heart when I see him doing things with her but in all honesty he doesn't seem interested.. last time o tried to talk to him about it we got into a pretty decent fight and he got really depressed. I know he loves her, he really does, but he seems to have NO interest in taking care of her! I think last time he even changed her diaper or made her a bottle was when I was in the hospital two weeks ago :( please... what should I do??
