> So, at the next stop light, I got out of the car and took my backpack. And started walking. There was a hostel in the neighborhood, so I asked for directions and walked there by myself.
A few hours later, I went back to where we had last seen each other, and he was still there. That was the last time he yelled at me during that trip.

So the strategy does work, you know that already :-)

There are less extreme forms of the strategy. 10 minutes 'time out' is probably enough for him to regain his composure. But the very act of doing it *every time* means that the behaviours will extinguish...

Works for toddlers...
Works for pets...
Works for husbands too lol ;-)

But yeah, sounds like you can do it :-)

(It might or might not generalise back to the rest of his life but not doing it around you would make your life a whole bunch easier)

Good luck.
