Hi. I (21f) and my brother (18m) got into it over a can of dettol disinfectant spray. So we have this disinfectant spray in the house that kind of bounces around and today I picked it up to spray a shirt. However the can was empty and I placed it on a small counter when it fell to the floor and I rushed out. Hours later I got a text from my brother asking why the spray is in my room. I explained what happened and he believed I was lying. So now my mother gets involved and we are now talking in our three person group chat. We are talking about it and my mom just says she will buy 2 sprays so it can be resolved. All of a sudden he starts insulting me and then I said "Fuck you" to then which he told me to "go die bitch". And I am not going to lie, I said some few choice words back. Side note: I am also unemployed at the moment and he uses that to leverage stuff he buys for the house. He then proceeded to call me stink, and basically mock me. What should I do?

Edit: I can post screenshots separately but I have to figure out how to do that
