My plan is to feed ego kibbles and stick to the standard responses
My plan is similar and is working pretty well so far. Never show stbx your hand. Pretend to be reasonable, fair & honest. I've always given him the impression that I will be amicable.
I pretend to want things I'm not really interested in, so when there is an opposition to something, I'll toss it in as if I'm giving up something I want.
Sometimes I act really appreciative and thank him for his generosity. It makes him feel like a big man. He has no idea how I'm working him.
I'm appreciative, alright...appreciative that I'm getting rid of him.
