HELP REALLY NEED OPINIONS!

So me and my fiancé got into an argument lastnight. He introduced me to his other side of his family that came to visit and he introduced me as “his girlfriend”. I thought it immediately and I continued to play nice and speak to everyone later when we left I spoke to him about it and he got upset. We argued and went to sleep I woke up this morning and we argued about it some more. It got bad to the point that he threw my makeup bag across the room and he took my ring off my finger. I got really upset and left the house and changed the code to lock him inside so he can’t leave. Super annoyed. Was I wrong?
