I think it is different escapes for different people. My W buries herself in the damn newspaper AND she sleeps way too much. The easiest way for me to get any attention from my wife would be to wrap myself naked in newspaper and go to bed with her...maybe then she'd take an interest in me.
The Sleep thing is obviously your W's way of avoiding the issues/problems. "Hey, maybe it will go away on its own if I withdraw long enough".
My issue is after 22 years of tolerating a Low libido W, I want more in my relationship and marriage. She'll be blindsided by my dissatisfaction in our marriage....I am struggling with how to approach her with this.
