You need to not worry about their feelings! They obviously don’t care about yours. You need to be honest. This is what grown ups do. Hey, buddy, all this dumping of negativity is really getting to me. I’m hoping we can talk about positive things, but if that can’t happen, I need to protect my own mental health. Every time they trap you with negativity, you walk away. Go to the bathroom. Walk outside, whatever you need to do. Life is way too short for this shit. You owe them nothing.
