My (29f) husband (28m) hit himself then threw his phone during an argument?

My (29f) husband (28m) of 2 years (in relationship 10 years but only moved into together for 2 and a half years) got into an argument in the kitchen and dining room area. He told me to just stop (talking) but I didn't fully hear hear him and continued. He told me again to stop and I made one more comment. He told me to stop and I did. I muttered something to myself and then hear him hitting. His head hard multiple times. I turn around and tell him to stop and that he doesn't need to be hitting himself (he's done this a couple of times before an did have too but I stopped doing it).

He then got up and threw what I am assuming is his phone into the living room a few feet beside him. He walked towards the door and I hear him toss something not as hard but still tossed something. He then left and I saw his phone on the floor close to the door. He has never thrown something before so this is completely out of character.

When he can back home (about 15 minutes later) I told him I did not like what he did and that he scared me. He began blaming me saying that he had told me to stop talking and that there was not reason to argue in the first place. He also said he doesnt understand why I'm looking at him all scared when he has never laid a hand on me.

I asked him to leave as I don't want to be with him anymore but he's still here just in the living room. I don't want to act like a saint as I have thrown things MANY times but it's not infront of him. I will go to another area of the apartment and throw something like my phone or punch the wall. I have hit myself in the past a lot but I stopped all these behaviors. I don't like that he threw something while I was there and that he is still continuing these behaviors.

I just wonder if this is something we can talk over or if I should just file for divorce.

Tl;dr

Husband hit himself in the head multiple times and then threw his phone twice while we argued. He had asked me to stop talking two or three times beforehand and blames me for not stopping. I have hit myself and thrown things before but I never threw things while he's in the same room as me and I stopped these behaviors
