Prayers to you Oz....did the dr. Give you a prognosis?
One thing I have learned is that even a good woman will stick by your side for only so long and eventually it will take a toll on them emotionally. Men are supposed to be strong, if your W percieves herself as being stronger than you even with this going on it will impact her. It's ok to share some things with her but maybe getting into a good IC would help you process some of your deeper emotions that you dont want to share or reveal to her.
