Help!

I’m starting to HATE my husband. The resentment is real and it’s starting to make me angry with him a lot. He started working a new job overnight and since then everything has changed. He started drinking more sleeping more and being lazy in general. But now he’s on a fitness journey so after already being gone from 5:30pm to 6:30 am (which was perfect because he could wake our oldest up for school and send him on the bus) but now he’s going to the gym everyday after work, so now not only do I have the kids all day while he’s sleeping and now all night while he’s working, I’m also having to wake up early everyday even though I’ve been up half the night with our girls ( almost 2 and 5 months) . So now I’m getting only around 4-5 hours of sleep. It’s honestly starting to feel like he’s purposely adding more and more to my plate so I snap and I’m so close! I’m ready to just quit I’m pretty much a single mom. He treats me like garbage and still thinks I should either suck him off or fuck him to keep him happy, yet I’m barely functioning anymore, I’m literally on autopilot at this point. My pp rage is “ getting out of hand” as he says but I’m just exhausted. This new job he’s not making enough to keep us afloat so I’m stressing out about bills and everything else on top of this. (I work a little more than part time and take the girls with me to work everyday) Yes I’ve tried to talk to him and nothing changes, I can cry my eyes out to this man and make him feel like shit and then it goes right back. I told him he needs to find a day job making more money but he refuses. So I’m just at a loss. I feel like at this point I’d be better off doing it all alone with just me and my kids.
