Can an abusive relationship be healed?

It’s always been up & down but today we got the most physical ever. We were arguing and I said “YOU…” when I said you I slapped his chest and he slapped me in the face twice. I Grabbed his arm really hard so he grabbed mine.

He doesn’t have any marks but my cheek is flared up and has a mark. My arm has a huge bruise already. It turned blue right away that’s how hard he grabbed it.

I know we’re both wrong but I don’t see how I can recover from this with him.

Our kids were at my moms swimming before summer break when all this happened. I never let them see us in our bad moments. We have three kids all under 4 years old.

I have stayed for the kids but after this I don’t see how I can continue. I’m heartbroken that our relationship has turned out like this.

Is there any way we could mend the relationship back together or time to call it quits? I love him but it’s so toxic. I’m so so heartbroken.
