I agree with TD , Meangirl and others, stereotyping is nonsense.
having said that, I think that women care more about things like a lack of love in the organization, which is easy for a man to dismiss, especially if he is an appointed man, he doesn't get the cold -shoulder etc. so that may be a reason why the Man stays in, when the wife already knows in her heart something is wrong.
The man will only feel there is a problem if he is interested in doctrine, or if he does get dumped on in some way, he will then look for reasons to leave, his wife, if in a good social group at the K.H with no big problems will be reluctant to leave, perhaps.
But all people are different, I think the old adage "He who generalise, generally lies" applies here.
I just feel sorry for anyone with a partner stuck in, it must be so frustrating and saddening, the life you could be enjoying together is denied you by a cult.
