Physical abuse

Hey girls me and my SO are 26 & 27. We’ve been together for 3 years now, after the first year the little pushes started to happen, the yelling at my face, the grabbing my neck just so he can get me to listen to him.. I’m just everywhere this past weekend he was drinking (not drunk) just two beers BUT any little bit of alcohol who knows what he’s capable of.. he threatened to kill us by crashing the car - we were driving home.. I have two kids from previous relationships. He has none

He started driving crazy on the freeway.

I’m just.. I’m just so afraid now..

we live together and I don’t know what to do.. we’re actually engaged.

Will he ever change? Can therapy help???

Ladies help me.
