I left the org. twenty years ago but my wife has stayed in. If you're willing to settle for less (much less) and can accept a compartmentalized life and relationship where the two of you can only share some of the compartments, then you can keep it going. But, it's unlikely to be anything close to what you want out of life or marriage.
To be fair to my wife -- and to any other JW women with ex-JW husbands -- I think the cognitive dissonance must be very, very difficult to deal with. Such a JW wife will, on the one hand, believe she is supposed to respect and honor her husband yet on the other hand must view him as weak at best or at worst as a more-vile-than-Hitler apostate. How can that work? If there are children, she will believe that they must be raised to respect their father even though she will view him as a constant spriritual danger to them and will, therefore, actively work to have them develop the same low viewpoint of their father as being spiritually weak and/or a Satan-inspired opposer as she has: if they become and remain JWs after they reach adulthood and move out on their own and then proceed to shun their father, she must consider this a job well done. She will read in the "Family Book" about the need for communication and spiritual sharing between spouses while at the same time believe that she must avoid all talk about anything much deeper than the time of day. While her marriage may once have been a source of status and acceptance at the "hall", it becomes instead something that makes her an object of pity, no longer one of the "in crowd", and may make her children be viewed as somewhat unclean and marked as possibly not good association. And as for normal friendly relationships with other couples, forget about it.
The result of all this and more of the same is likely to make her view her marriage as a trial that she must endure. And who could be surprised if, to relieve the constant pressure from trying to reconcile these mutually contradictory beliefs and feelings, she increasingly simply pays lip service to being a "Christian wife" while in her actions and manifest feelings she is wholly consumed by the JW-inspired negative view of her husband?
