I'm wondering if this is a cool strategy for everything.....
Live my own life, keep being a good H, keep marching forward with researching solutions BUT not be secretive about...be blatant but don't talk to her about anything. Simply wait for her to "sneak a peek" at the Sex Diet book in my nightstand, or chime in with "can I go to the therapist with you?".
It's an interesting idea...kind of like..."I'm working on this with or without you and I will be a better man because of it".
