Advice on relationship

My fiancé hit his head on the fridge tonight and started cussing, and I was letting the dog in (he doesn’t like the dog) and he said shut the door, I said I’m letting her in and he said I’ll punch you in the fucking face. I said I’m leaving don’t talk to me like that, he said bye. Then when I said you told me you’d punch me in the fucking face he said I was just joking.

Advice???
