what would you do?

Okay so sorry in advance for being long but I'm a half an inch from loosing it.. back story my so and I lost our jobs in Sept of 2016 he found a job and so did I the scedule I was working wasnt working for me *had a 9 month old at home and no one to look after her* fast forward to November I quit working the beginning of the month and we had to stay with my parents because we weren't making ends me and had a baby at home in the midst of me job serching my grandmother passed away and my dad lost it ended up throwing me and my so and daughter out we thankfully could stay at his parents *at that time it was temporary* I found out in was pregnant again I still continued to look for a job but wasn't having any luck plus i had no one to watch my daughter his parents eventually talked to us and the agreement was I took are of the house, kids, and food I didn't have to go back to work and my so had to cut the grass, do the trash, pay lights, enroll I school, and go to work. Here's the problem I can't get him to do anythin at all I'm at my wits end he won't even help me with our kids it's a fight or argument or if one of the kids are screaming he gets mad and it pisses me off he acts like they have no reason to cry he is in school online and does work so I understand he wants free time but I'm going crazy doing it all by myself I feel like a single mom with a roommate.mand don't say cut him off its been months since we've done anything remotely intimate does anyone have any advice as to what I cam do to get him to help me more
