Unless you want a life of being his mother, I advise that you draw a line now. Right now. Today.
If he abuses you because you won't be his mother, that says a lot about him. Is that the life you want?
My parents have been married for (not as long as they say they have, but that's another story...) years, anyway. Together for 35 years.
My mum does all the cleaning, runs round after my dad, makes the food, gets him drinks, puts his socks on for him.....
My dad sits (lays) on the sofa and asks my mum to get up - from the sofa - and fetch him
a drink
a sandwich
the telephone
the remote
a book
a tissue
etc
etc
etc
My mum does it. She's always done it. He expects it now.
He's a slob. His office at home (which my mum does not go into) is full of glasses with fag ash in them, about 20 at any one time. A dozen or so plates - from the food he has PHONED MY MUM FROM UPSTAIRS TO ASK FOR, A thick layer of fag ash on everything, mess everywhere (not to mention the cat shit)
Eventually, when he's no desk space left he brings the glasses/ashtrays and the plates/ashtrays down (shock horror) and leaves them on the side.
For my mum to wash.
When she moans, he does a bit. But he does it so badly that she has to redo it. Then he says when she next moans.....
But when I DO help, you only do it again, what's the point...
The only difference between him and your bloke, is that your bloke is verbally abusive, whereas my dad is mardy and puts on a whiney 4 yr old voice when asking mum to do something. It's pathetic.
I am more mad with her though.
Welcome to your future.
