Thanks for your post.

She meets all the conditions for schizoid from the DSM IV.

from www.pipeline.co website:

neither desires nor enjoys close relationships, including being part of a family

almost always chooses solitary activities

has little, if any, interest in having sexual experiences with another person

takes pleasure in few, if any, activities

lacks close friends or confidants other than first-degree relatives

appears indifferent to the praise or criticism of others

shows emotional coldness, detachment, or flattened affectivity

has a childhood history of grossly inadequate, cold, or neglectful early parenting, which often began early in life. These traumatic experiences create an expectation that relationships will not be gratifying and a subsequent defensive withdrawal from others.

Intrusive mothering, detached fathering.

Basis belief: I need plenty of space
Strategy: Isolation

All this fits, she has been to a counsellor who has not been much help. I know it will take time. It does seem the best thing at this point is to give her space. She is around people of faith who give Christian counsel to work on the marriage and herself.

Thanks again
