I dont know enough details, but there are plenty of us on mn who are or have been, married to control freaks, and what we all have in common as far as I can make out from other peoples posts, is that we were fooled at first!
Then, there are often reasons why a person doesnt immediately leave a controlling relationship (kids, long gradual realisation of how awful it is, low self-esteem, poverty etc). So I would NEVER assume that a person is happy to be the submissive partner in a controlling relationship.
