Is one tiny slap really enough reason to break up?

Anonymous

My boyfriend and I had a fight the other day, about my younger sister who has managed to get pregnant at 17 and he had ZERO sympathy, said she did it to herself because she sleeps around and I didn't think I immediately slapped him across the face for speaking that way, and he immediately told me to get my stuff, get out, and never contact him again.

I told him we can talk in a few days when he calms down but he told me that we are over, and called me abusive, but I think this is a massive overreaction.

We don't live together, so he hasn't kicked me out on the streets, just out of his house where I had a few things.

I've tried pretending that what I did was wrong and apologising but he won't reply, I think he may have even blocked me.

I'm pretty sure I would never do it again, it was just a heat of the moment thing.
