Fiancé refuses to get a job

I've been tempted to right this for months now and I kept telling myself no, it's not a good idea to vent on the internet. But ive gotten to the point where the straw has broken the camels back.

Right now my fiancé and I live with my mom who's bed ridden with MS and my 30 year old sister who has autism. My fiancé moved into my house with us because we were trying to get pregnant and we got engaged! Everything was going relatively well and I was excited to finally be living together, whether it was here at my moms house or not. Well my fiancé quit his job back around January or February after he moved in because he didn't like it and months later lost his car as well because he couldn't afford the payments. We were both upset but I was personally upset at him for up and leaving a job just because he didn't like the type of work and it "hurt his hands and back". Mind you he was folding boxes 🤦🏼‍♀️. Fast forward to now, beginning of September, he still has no job or car. We have our little girl who's 7 weeks old now and we have 0$ income. He's told me he's been applying online for jobs but the other day he also told me he's ignored phone calls to interviews. He's gained some weight and sleeps all day in bed now. He refuses to work, he refuses to change a diaper or bath our baby or help put her to sleep, he refuses to do anything. All he does now a days is sleep, eat, or play video games. The way we pay for things is with my mom giving me money for helping her or his mom sending him money. But he spends that money on food and drinks. I've also been struggling to make my car payment and my credit card payment because of the situation were in.

Im so pissed off about this. Before him I was working a $16 an hour job, I was close to getting my own studio apartment, I had my life thriving! And I was excited to start a family and get engaged. But somewhere down the line he just... lost it all. I don't know what happened to him. And now because of him I have nothing, no money, no job, no nothing. I'm so mad that he's put us in this shitty situation and I'm

more mad won't do anything to resolve it. What the hell do I do.
