It's not always me bringing up the serious conversations, he does it just as much. I know today I started, but with the previous talks it was mostly him. So I'll try not to get drawn into conversation like this.
Regarding that boundary, how can I enforce it at all if he just drops a rude/accusing/hurtful line and that's where it ends? I can't leave the conversation if he already left?
