Try the book, "Getting Back Together" by Bilicki and Goetz. It's cheap at $9.95 but provides a wealth of information, including how you can reconnect with yourself (very important) and stuff for getting back together with your spouse. The book deals with the point of view that the two of you are separated, but I think you can get it to apply to any type of living situation.
You may also want to check out "The 5 Love Languages" by Gary Chapman. It will help you to understand how your W expresses and receives love. I think it is such an eye-opening book that I give it out for wedding and anniversary presents now.
