Relationship issues

So about a month ago my fiancée was upset with me about our relationship. He started yelling at me, getting in my face. He drug me out of my car. He pushed me up against a tree and then when I tried getting away from him he threw me again his aunts car. I got Vertigo from him doing this to me. I didn’t press charges or get anyone involved. I just let it go. We do have a 19 month together. I’ve having a hard time deciding if I wanna stay with him or leave him because what he has done to me. Part of me wants to love him and another part of me says “NO” because of what he’s done. This is really embarrassing to tell people.....but I need to

Figure out what I should do.
