Being with a man child...how many ladys here have one?

Alright ladies so I've bought had it up to my eyeballs with my Boyfriend's lack of respect. He leaves trash everyyywhere, and his dirty clothes and socks wherever he decides to take them off. I work outside between 12-14 hours a day. Right now it's friggen freezing cause it's winter in New England...he had the day off I was texting to him how tired I was and how cold it was yesterday and he gave me sympathy. But then I come home and it looks like a bomb went off. Mind you this bomb went off days ago but I was waiting for him to do something...mistake cause it piled up. Anyways he said he's lazy and gaining weight cause I bully him. Then blamed it on I don't support him, then blamed it on I'm not affectionate enough. I know y'all don't know my relationship but those sound like excuses right? What the hell can I do to so he changes his habits? I had thought of copying his bad habits so he'll understand why I don't want to have sex with him. Any man that doesn't keep is himself and surroundings clean

is not attractive to me sry. I also thought of getting a sex doll except it's the headless, armless, legless ones cause they cheaper and easier to store. When he finds its huge cock and chiseled abs he might wanna change his lifestyle. But idk please help...
