Do you & your SO communicate well when I’m arguments?

Okay so when something is bothering me or when my SO gets me mad I tell him what it is I’m upset about & recently he ALWAYS.. EVERYTIME will fire back with how I’m not perfect either & I do the same “said” thing. It’s honestly getting old so I called him out about it & his response was that when I do “said” thing he doesn’t say anything bc he doesn’t want to argue or because it’s something so little. So if he’s going to ignore it at the time it’s happening he shouldn’t bring it up when I’m expressing how I feel right? Because then we’re just going back & forth about his past feelings & my current feelings. Am I wrong? Because this is getting hella annoying & I don’t know how to talk to him about it anymore, It’s draining.
