Have you tried beginning with small, physical touches? Pats or strokes on the back. Using that type of thing for jobs well done or similar? How DO you normally show appreciation of someone other than a hand shake?
How is this non-touch behaviour different than what it used to be before your M went south?
It is often stated that women don't go physical until they have the emotional... is it possible that your W is still not feeling the emotional connection and intimacy that she might need?
Are you paying attention to her ALL THE TIME? IOW, is your relationship still a matter of you and her having short moments of "togetherness" and you never make the time to just BE THERE for her to listen and validate / affirm?
Have the two of you gone on any "dates" just the two of you? How is that different than when you first met?
