I agree with Zoe Girl... when I read enota's post I wondered if she and hub had been evaluated for depression.
There is a Depression Fallout discussion group, which was begun by the late Anne Sheffield, author of
Depression Fallout: The Impact of Depression on Couples and What You Can Do to Preserve the Bond
Actually baby boomers are increasingly choosing the option of "gray divorce" rather than preserving the bond. ...especially those who had previous marriages that ended in divorce.
I would not minimize the financial and self-esteem issues that can arise from a gray divorce. Heading into retirement, the assets and incomes which supported one household would have to s-t-r-e-t-c-h to support two households.
There is a database (you have to pay a membership to get into it) of people who are looking to buddy-up on housing... either as a room-mate/companion or as a landlord. Typically these folks are 50 to 70 years young... many have gone through a gray divorce to arrive at their present need.

May I suggest an affirmation?
You are worthy to live a good life in a relationship that is fulfilling. Take license to enjoy creating intimacy, connection and companionship that feels good to you.
