Good luck, at least it seems you are being able to part on somewhat amicable terms. In my own experience, loosing a marriage is hard, and whilst my relationship was about 10 years, yours was 31 years, I couldn't imagine that. At least no one is being put out on the street and from the sounds of things you aren't hating her for the way she feels, you actually seem to be putting forth good effort to understand and empathize.
