You are right that your W will find another way to contact the OM via smoke signals, etc. as long as she is attracted to him and not you. And you will continue to obsessed with the sitch as long as you spy. It took a 2x4 from soleil and others to get me to stop spying on my W and once I did I was able to focus on me.
What are you doing to change the dynamic in your R? Yesterday,you showed your W a real man! I am not sure if she menatlly mature enough to compare the man that she M to the man-boy that she is fixated with, but if she is not then maybe she is not worthy of you. Hold the high ground and take away the comforts that are not necessary to live your life!
