You know, the guy who’s been having that same angry conversation about the same fucking thing he’s been obsessed with for the last 5 years and demands that you take his view while going on long monologues and then immediately interrupting anyone who tries to get a word in edgewise? And then goes into a weeks-long suicidal despair if you try to leave the conversation? Any way to deal with that?
Be honest before inviting them, that if they behave that way they should stay away. Any suicidal ideation should be discussed with their psychiatrist. There is no shame in cutting ties with toxic people.
