Don't worry. Initially it took me a good 6-8 months before I was ready to just stop all together. There are a lot of "moving parts" in your psyche around the issues and they neeed time to allow your cocnscience to reconcile them. Believe me, you will do yourself more harm than good trying to force yourself - the false remorse, feelings of guilt, etc are all "normal" only from your current plane of reference. My wife left first (2 months before me) that was not easy at first, but i have come to be grateful to her for taking such a course.
It will all work out in the end!
