Sorry to hear you're going through such a tough time.
My advice would be for you to follow the advice of the book and work on solutions to the problems that you two are having. Also going to see a good therapist would help as well.
Am I correct in inferring that you want it to work out, but you need to see changes on his part before you're truly ready to recommit?
