Has your significant other cursed at you while pregnant?

me and my fiance get in disagreements and he’ll say “ bitch” or “fuck you bitch” and i’m 11 weeks pregnant. I seriously am debating leaving but I feel stuck because of our apartment lease and don’t want to be a single mom. Has anyone ever dealt with someone cursing at them while pregnant? Does it get better? he’ll immediately be like “I’m sorry I’m sorry” but next argument, it’s like repeat. Yesterday , he even was like “ don’t throw up in front of me” because I was gagging (I been throwing up so much)
