Heading for divorce

My husband and I just had a baby 3 months ago and I would say I've been thinking about leaving him about 3 months before our son was born. Our problems started when I started getting morning sickness and being tired all the time. He'd always make a comment on how I'd sleep all the time. First trimester ended I quit being so tired and the resentfulness went away until my 3rd trimester when I was just hurting to much to work all day and then come home and clean or cook. My husband has always been the type to have the worst day or worse pain. Its almost like I'm not allowed to be hurt or sick. When I first went back to work after our son he still expected me to do everything. I started resenting him for it and for the first time I told him I had doubts about us. He comes home from work and plays games on his phone and ignores us half the time. He said he'd work on it and the same night he makes plans with someone else knowing its been over a month since we had a day off together (he's really trying huh?) spend up to now. I hurt my foot in a boot and crutches now and my grandmas in the hospital 30 mins away. I ask for a little help around the house and a ride up to the hospital and its a big deal. Even though when his grandma was at the same hospital. I drove up there everyday to be his moral support and he couldn't do it for me once without complaining. I want him to care for me like I do him and I just don't see it in him. Am I asking for to much? He should want to help me out. It didn't feel like a burden to me when I was doing it for him.
