I don’t know what to do

My bf has this kid who is trying to sell him acid so that my bf can sell it. He’s trying to sell like $500 worth of it to my bf. I told my man last night that it made me uncomfortable and I didn’t want that much drugs in OUR house. We didn’t talk much after that. Then this morning (on our anniversary by the way) he was acting all excited and comes up to me and goes “the kid is willing to sell the acid to me for even cheaper.” And tried to give me a high five. I shook my head and said “I told you I didn’t want you doing this” and he immediately got an attitude and said

“I didn’t ask if you wanted me to do this. I can do what I want”

Ive never had a person talk to me like that before. Never been so disrespected. So then he basically threatened me and said “if you keep talking about it I’m going to scold you. So you’re just asking for me to yell at you if you keep talking about it.” But I said I wanted to talk it out so there is an agreement. He said that there won’t be an agreement and the talk won’t end well and to just drop it. Then I just said “well I..” and he yelled and said “oh so you want to be scolded? Cool keep it up” so I stopped talking and went into our bedroom. Idk what to do. Idk if I need advice or support or if I just needed to vent. Am I over reacting for not wanting that In our house we both pay for ?

DISCLAIMER**

I am not and will not call the cops. I’d only call the cops if I felt my physical safety was in danger and there was nothing I could do about it. I obviously can leave if I chose. So cops is not an option. Sorry lol
