Hang on, I thought he was happy that you didn't want to marry him anymore as you would stop going on about it.
You would be a total fool to stay with this man. He is vile to you. Calls you names and thinks you are beneath him as he has this huge magic proposal to bestow on you when he deems you have served him enough to deserve it.
Do not get pregnant, stop doing all domestic crap for him and get yourself to the solicitor asap or else accept your shit life and stop moaning.
I expect it goes like this in your house
You shop, cook, clean, do the washing, all the childcare, fuck him
He eats the food, dirties the clothes, maybe speaks to the kids occasionally, lets you.
Come on love. You deserve better.
I know what it is to want marriage and kids. I had a shit, abusive childhood and wanted the security that I thought marriage would bring and children so I would have love to give and receive. It worked out well for me but it will not work out with this man. He just doesn't think you are good enough to be his wife. Well let e suggest he isn't anywhere remotely good enough to be your husband.
