Relationship advice

My boyfriend and I got into a disagreement on how something should be handled Thursday. I tried to end the conversation about it by just agreeing because honestly there was no need to argue over something so little. He kept going on and on about it after I told him I would do it his way and asked him to drop it. He literally got on my last nerve because he kept going on about it so I yelled at him to just drop it. He got upset and told me I should leave and go to my moms house cause he’s not going to deal with me yelling at him and threatened to call the police on me. He has done this more than 3 times now and I’m tired of it. He says he’ll call the police on me but then comes back later and try to apologize like he didn’t mean it. The last argument we had before this one I told him how that makes me feel and he said he would not do it again going forward but here we are. We have been living together going in 2 years and have been talking about engagement and marriage happening soon. I expressed to him that him doing this makes me feel like I’m not safe in this relationship because every time we have an argument he will threaten to kick me out and call the police on me. All he does is say sorry and think that’s supposed to be enough and I’m supposed to just drop it. This is what he sent me 👇🏾
