The first thing a FT needs to straighten out is your H's interpretation of "control"

Your H's idea of being controlled is someone NOT supporting him doing whatever he pleases.

It seems that whenever he wants to do something that causes conflict, he accuses you of controlling him...

He need to learn how to spell "cooperation" and "negotiation"... accusing people of controlling him at the drop of a hat at the slightest sign of discomfort is passive aggressive BS and he needs to grow the hell up.
