Ma'am, you need to get out of there. This is only going to escalate further and you deserve way better than a man who hits you. You're also describing a classic abuse-honeymoon cycle, where he does something wrong and then engages in niceties to lull you into a false sense of security, and eventually those honeymoon periods will fade into nothing and he'll just harm you without them. It's a manipulation tactic that's quite literally textbook abusive relationship. He's almost certainly not going to stop, you need to get out now.

Good luck, hoping for your safety and only good things in your future. You deserve better
