Another way to look at it is (if you are religious) to realize it is not God's plan for me to be alone the rest of my life. So, either my W is going to wise up and want to work on the M or there is someone out there who needs me more than my W. Either way, I end up in a better relationship - either my W and I make our M what it should have been or I "Do the work" on me and end up in a better R than I ever thought possible. No downside, man.
How appropriate I should read this today. The mother of one of my daughter's friends asked about my sitch. She asked if H was cheating, and I told her it didn't appear so. Her response...then you better beg him to come back because you'll never remarry with all those kids.
So there you have it folks. I'll just become a crazy cat lady.
