Would you be willing to share the sites and book you are reading?
Absolutely. This site has been posted in several threads lately. http://www.coping.org/control/detach.htm. Don't just read the article on detachment, read the other articles as well (letting go, caretaker, need to fix, need to control). Chances are if you are struggling with detachment then you are codependent on your S. "Codependent No More" written by Melody Beattie can help you with that. But, it also has several chapters that address detaching, that helped me out tons. Another book that has helped me with detachment, forgiveness and and all around better relationship with my wife is "How To Heal A Painful Relationship" by, Bill Furguson. I hope these can help you out with your R as much as they are with my own.
