My boyfriend curses at me what should I do?

So my boyfriend says stuff like "I can do whatever the Fuck I want with my money" because he lost majority of it in crypto. And like his phone broke I said gotta be careful not to put your phone on the sides of the sofa so he said "How the Fuck I was supposed to know it was gonna break?" So yeah I told him not to curse at me and I'm tired of it. Nobody talks to me like that. If he says it again, I'm gonna tell him I'll leave or just leave. It's not hard asking him to NOT curse at me over the dumb stuff he does. Just a lack of respect.
