Here is something coming from a man's perspective.
Sometimes the best control is no control at all, the WAH dosen't control and lets the OW think she is in control. As long as she thinks she is in control she will stick around.
The WAH lets OW take over bill payment and make decisions because that stuff is work, it requires thinking and they don't want to do that at this time.
WAW is exactly opposite in my opinion, they are looking to control someone as they have the perception they have been controled in thier M.
