communication

hey ladies. So my boyfriend has been very quiet when he's mad lately. He gets mad and then just shuts me out. He gets his phone and doesn't talk to me. I have already told him to tell me what he doesn't like about me at the moment because I hate when he stays quiet, I think it's very childish. I told him that yeah, it's gonna hit my gut if you tell me what you don't like about me or what's bothering you, but I'd rather have a conversation about that than him shutting me out you know? Idk what to do
