He wants me to move because things are cheaper over there, I could get a nicer apt for less money. There's a safety net, free health care, subsidized child care etc and its where our families are. But if I move there, I'll move to a city I'm not really that familiar with. I have no friends there, just a family member and I have no desire to live and raise my D there.
I've lived in the US for more than a decade. It's what I know and love. It's where my friends are etc.

I can't deal with him changing his behavior on a whim like this. One minute we're friendly, the next he says he doesn't care if I end up hating him for a long time because I have to move - it's the smart thing to do.
