Yes, in the sexist view promoted by the WTS, the woman is a "complement". The completeness of the MAN is the important thing in the congregation. Marriage helps toward that end, in the JW's view.
Their deliberate misapplication of 1 Corinthians 7 -- to "marry only in the Lord", is a sure mark of a cultish religion. That scripture was talking about remarriage, but the WT Society adds on its own thoughts to this verse (to stretch its meaning to apply to all JW marriages) and so many others to suit its purpose.
Where are trained counsellors for people with marriage problems in the JW organization? The elders training consists of schools where they are told to encourage more JW activity as the resolution for most problems. That's no help at all. The rank-and-file Witnesses are discouraged from seeking helpful professional counseling when needed. Somehow that would indicate a "lack of trust in Jehovah" and open them up to "worldly" ideas. So the JW's with various problems (like marriage problems) just have to tough it out, and it doesn't always work out very well.
