Kevin, I'm not pretending to speak for anyone but my own take is this:
Sure, we're all social animals, we want interaction, affection, and love. Want, not need. We invested a LOT in Ms that went south, many of us here, to the point that co-dependency could be an understatement.
Our sitches woke us up to many things. We had to become whole again as a person to come out of it all. We learn to accept what we can't control, which includes choices and feelings of our WAS and / or future people in our lives.
We know our lives can be meaningful, important, relevant, irrespective of what others choose to do.
Detaching has nothing to do with the value others bring to your life; it simply means you let go of trying to control the who, when, why and how. It helps you become a person that attracts the who you want, and hopefully the when, how and why follows.
