Someone talk me out of smothering my boyfriend with a pillow...

EXTREMELY pissed off and annoyed right now... I’m 22+4 weeks pregnant. I have a 12 and 10 year old, work in a nursing home (yucky job), and when I’m not working I’m constantly on my feet cleaning up after everyone... mainly my boyfriend. He’s a chef, and when he’s not working he’s either hanging out with our neighbor, playing xbox or dicking around on his phone, or he goes and lays down and goes to sleep. In the meantime here I am almost 6 months pregnant doing ALL the housework including his ridiculous amounts of laundry. To top it off I also have MS and have been having complications with this pregnancy. I spend all my time im at home cleaning and trying to catch up on all the laundry. Constantly have to clean up after my grown man of a boyfriend who can’t even walk five feet to put dirty smelly clothes in the hamper and instead shoved them under my bed. He comes home from work, complains about how hard it is being a chef (😂😂😂), hangs out with the neighbor smoking pot and shooting the shit, takes a shower right when I am trying to get in myself, then either plays games, posts dumb shit on Facebook, or just goes and lays down to go to sleep. Must be nice! Every single night he throws himself around on the bed like a child throwing a tantrum when he can’t get comfortable waking me up, constantly in and out of bed keeping me awake. As if it isn’t hard enough for me to get any sleep between being in constant pain, the baby kicking and waking me up (I really love that though ❤️), and having to pee every hour. I’ve been asking him since thanksgiving now to help me get my Christmas decorations out of the garage, but everyday it’s “I’m gonna nap wake me up in an hour and I’ll do it” or he just goes to bed after barely speaking to me. Can’t blame him for not trying to talk to me cause most days when he gets home I’m in a horrible mood cause I’m miserable and in pain and at that point I have spent my entire day cleaning up after his lazy ass. I will add that I have OCD, but I’ve let a lot go. But I’m terrified of what my home will look like when this baby gets here... especially when I see what this place looks like when I get home from work 😡😡😡 I’m so sick of this shit. He barely ever offers to help me anymore. Most days I’m in too much pain and too exhausted to even take a shower!!!!!! Today alone I spent two hours folding HIS LAUNDRY. Not even mine and my kids. He didn’t even thank me. I waited all night last night for him to help me get my Christmas stuff out of the garage all for him to not wake up and sleep from 6pm-4am. Then he acts all lovey dovey like nothing is wrong. I’m so done! At this point I’d honestly be better off with him out of the picture. At least then I wouldn’t have to clean up after him. My kids ALWAYS offer to help and it’s so sad and pathetic that they clean up after themselves 100000 times better than my boyfriend does.

Any input that might work here would be appreciated. If not then at least I got to vent! I’m just at my wits end and it’s all building up and I’m about to snap
