Need advice! Should I end my marriage?

I am 8 months pregnant. We came back from a party, and I brought his families behavior at the event because we were the hosts. He told me to drop it, then started shouting. I said something like “you have a speaker in your neck and just raise your voice when there is nothing to say" and called him useless. He came and grabbed my face asking why I said that and he has told me a lot of times not to say it as I do tend to say that in frustration

I stepped out to avoid him. Then I don't remember what was said but he came too close while speaking, I pushed him and dug my nails into his chest in anger. He slapped me really hard, my ear still hurts.

Now he’s apologizing, hugging me, but still says I provoked him. He said I hurt him and it was a response to that. He did not believe me when I said that my ear hurts and called it a drama.

I feel guilty, confused, and also scared. I’m seriously thinking of leaving but it’s overwhelming. I just need clarity. Should I give my marriage a chance ?
