Why is this happening? 😩

I feel so depressed lately, my boyfriend (well meant to be fiancé) hasn’t been near me for about 2 weeks now it’s getting me so down i just feel like I’m in a circle repeating my day over and over again.. I get up feed the baby get spoken to like a piece of shit by my boyfriend, look after the baby for the rest of the day while he does whatever he wants, he don’t want to get a job so money’s a big struggle, he’s rude to everyone In my family, he speaking to me like I’m a piece of crap, he don’t want to go anywhere near me... I don’t understand we was so good now all of a sudden he’s changed.. if I tell him I don’t want to be with him he to threatens to take the baby I can’t win I feel like I’m stuck does anyone have any advice? I really don’t know what to do
