My #1 tip on detaching is to replace the ways in which your W met your needs with alternatives.
For example, if you miss the physical touch, get a massage 1-2 times a month for a few months. If you miss the emotional connection, post here what you'd want to share with WAW, or spend more time with close friends. If you miss family time, make some special time with your kids or with relatives you haven't seen for a while.
What you will find is that your W is just a person. When we've spent so long with them it's easy to see them in a mystical light, as if they hold the keys to our soul. But the truth is that when we diversify how we meet our own needs, they will no longer look magical. Once our needs are met, she will look more like a person we'd like to spend our life with, but not salvation in itself.
That is why GAL is so important. It gives you opportunities to discover other ways to meet your own needs.
