BF said I had no boobs under his breath during sex and then slapped me hard in the face.

I am 30F bf is 32M.

We live together and plan on getting a house soon. I don’t think I can continue the relationship after this. He has shown abusive tendencies in the past but I thought he could improve. He will move into his house and I will keep the apartment. I probably won’t be able to afford it by myself. I just met his entire family a week ago. He is the only boy out of 7 grandkids; so all female cousins and he has a sister. He apologized this morning but has been acting selfish otherwise the rest of the day. Nothing nice he can do for me.

TL;DR: bf abuses me and I want to end the relationship
