Single parent in a marriage

My husband spends all his time on his phone, in the bathroom, in the tub, or playing games. Once in awhile he will fix supper or do a random load of laundry but thats it. Anytime I need help with the baby he tells me to give baby to one of our kids (2 of which are teens). I've told him no repeatedly because baby is our responsibility not theirs. The other day i was talking out of my head from exhaustion and so he told me to nap. This never happens so i did thinking he had baby. Instead he took baby and dumped her on her siblings even though she was crying the entire time. It doesnt matter if one of her siblings are holding her right beside him and shes crying he will ignore her and just turn up his tv show. I do 99% of the parenting and the house work. When he does parent its stuff like taking away his teens phone because she doesn't give him enough hugs. Like what?? He's grouchy to me and the kids most of the time. Then saying snarky stuff about me never wanting sex and that I don't even like him. I'm so tired. I've tried talking to him repeatedly and it's always the same. "I'm sorry" "I didn't know" "You have to tell me when im doing these thing's". I don't have it in me to parent my husband. I'm just done trying to make our marriage better. Is there any hope in these situations?
