My(30f) bf(36m) takes my ring everytime we fight?

Bf and I have been together for a little over a year. He got me a promise ring a few months into dating. I loved it, it's beautiful. I have never taken it off myself. I see it as a symbol of my commitment to our relationship.

But everytime we fight, my bf will say hes done, ask for the ring back or straight up rip it off my finger. I used to ask for it back after we made up after the arguments. But last night really doesn't sit well with me.

We went to the store to pick up some last minute things for our own little thanksgiving dinner. We walk in, and I'm trying to look down the aisle in front of us to see if what we need is there. There are 2 guys standing by the aisle. As we walk past them my bf says "remind you of your ex?" With a grin on his face. I wanted to make sure I heard him correctly and asked what he said. He was walking ahead of me and said it again. I still didn't hear him so he got mad and said hes not repeating my exs name again. We shopped in mostly silence after that.

When we got home I put the groceries away and went into the living room with him. I realized now I should have chosen a better approach, as I started off with "why did you seem irritated?" Which he said I came off accusatory and why he reacted hostile towards my comment afterwards. He said he wasn't irritated. I said okay, went to get up and ge asked if something was wrong with me. I said well yes I am irritated at what happened at the store. I thought he snapped because he kept bringing my ex up. He said he snapped because i wasn't hearing/listening to him. Turned into an argument and I decided to go back to the kitchen and start on food. He said to not make him anything so I said okay I won't make anything as I wasn't hungry. He got up and told me to give him my ring that he was done. I said no, I love the ring. And he came up and grabbed my hand and said he didnt want to have to break my finger taking it from me. I didn't fight him on it. Let him take it.

We argued for about 2 more hours. I tried to tell him my perspective on it and why it bothered me, he just said I was attacking him and proceeded to attack me back.

We did eventually calm down, talk it out and make up. I realized that he unfriended me on Facebook and he said he was being serious in the moment. It hurt my feelings a bit, because we had just had a talk about engagement stuff the day prior and how no matter what happens we always work to be better for eachother. But then this happens...

I have not asked for the ring back this time, I honestly don't know if it's worth it, even though the ring to me held a lot of purpose.

I'm not sure what to do at this point
