Boyfriend problems 🙄

Just curious, how does your boyfriend react when he gets mad at you?

My boyfriend hasn’t always been like this AT ALL but now (since being quarantined) he likes to scream at me, threaten to move out of our apartment & leave me, & he also likes to cuss when we argue. He tells me to “shut the fuck up” & called me a dumb ass. Now I’m not gonna lie, I was telling him that he was dumb & telling him to shut up...but I don’t ever cuss at him like he does to me. I really feel like he’s disrespecting me as his girlfriend. I need input 😪
