I didn't understand how mine of (now) 31 years could walk away from ours where I make 4x the money and he doesn't have a viable plan B. I finally got it through my head that it isn't required that I understand it. That is the way to freedom from the craziness. I firmly believe now the only way forward to to accept things as they are right now, give them what they want (freedom) and remove your presence. How that takes shape in your situation, I don't know. I didn't have kids. If they are going to see the error of their ways, it isn't going to be while you're still in Plan B mode. The veterans here all say that and it's easy to accept in theory but hard to put into practice. Everyone has a stop loss (to use a market term) if they have any functioning regard for themselves. Where's yours? Mine hit and I walked away. And now mine is sort of creeping back in this direction. I don't care. Until he is all the way back, he's just another acquaintance that I may or may not engage with.
