Abusive? Am i just crazy?

I’ve been with my now fiancé for a year now. He’s always made me so happy, or atleast at first. He has a 7 year old daughter and they both stay with me now (when she’s not at her moms). I also have 2 sons one is 2 & one is 9months. (My kids dad left me when i got pregnant with my 2nd , me and my fiancé got together in September of 2018) So ever since he’s moved in he doesn’t pay any bills, help me with my kids yet i treat his daughter like she’s my own, he doesn’t do laundry or clean. He doesn’t clean up after his daughter either. When i bring up that i do it all myself he basically will go off and curse me out saying I’m ungrateful and don’t appreciate him and start going off because “i shouldn’t expect anyone to watch my kids for me” and other random shit which i don’t expect anyone to watch my kids but I’d you’re gonna marry me treat mine like yours and yours like mine. His daughter can make huge messes and if i bring it up he defends her saying she’s a “baby” and it’s not her fault. She gets everything she wants and does nothing to earn it. He showers with her, brushes her teeth, lays her down on the bed dries her off & dresses her. He doesn’t allow me to have any opinion at all. I told him i personally don’t think some of that is normal he flipped out on me. Called me names and just went crazy.

Anytime i tell him something that bothers me he goes off on me. Like for example earlier i told him i wanted to be unblocked on Instagram and he said “i don’t know why it’s such a big fucking deal” and when i asked why he’s mad he said “i wasn’t but now i fucking am”. Everything i say or do makes him mad and he cusses at me knowing i don’t like it. I’m going through a miscarriage and the last 2 days he hasn’t even seen me because he’s been out all day with his daughter which i know he wants to see her but I’m struggling a lot and in pain and he’s acting like i don’t exist because she’s around. Two days ago i showed him i had a positive pregnancy test and he told me i was just trying to start drama, said I’m lying about being pregnancy to “tie him down” and calling me crazy and he literally broke up with me because of it. Then i started bleeding like crazy. He breaks up with me 5 times a day , he tells me he loves me and wants to marry me and something will set him off and he’s done with me without even attempting to talk out the issue. Then he says he doesn’t mean it and loves me but if i tell him what he did wasn’t okay and it hurts he’ll just leave me again. I’m scared to tell him anything. He says he’ll change then he tells me he doesn’t care what anyone thinks. Some other examples is hell want his little sister to spend the night and if i say no because I’m already dealing with my kids and his kid with no help he goes off saying I’m selfish and he doesn’t want to be with me. He’s 25, his sister is 12 and is extremely loud and i have two babies who are already hard to get put to sleep. Not only that but she’s left period blood alllll over my bathroom so many times, i told him and he got mad at me saying its not a big deal. One time we had sex and i told him i didn’t cum and he started yelling “why do you always have to fucking bitch”. He told me last week he wanted to take off work Thursday because we hadn’t seen each other much and he works for himself so he’s capable of doing it , and it was his idea and all week i looked forward to it because i can’t ever go out and he texted me saying “do you care if i don’t take off” and i said “well i was looking forward to it but i know you’ll do what you want either way” and he was like “okay then I’m gonna do what i want and not take off”.. constantly, it’s something. I’m always being gone off on or let down.

Every other word out of his mouth is a curse word. Me expressing how i feel is called “bitching and complaining”. Im walking on eggshells and constantly scared on edge and stressed and idk what to do and idk why i love him ....
