She made the "offically separated" comment because I asked about our sex life and it was not a "good time". There is never a "good time" to discuss it or actually have it. So because I pushed to discuss it, she replied with the official separation comments. Granted, it was late at night after I realized that again she brought up sex, but nothing would occur.

You touched on the "pretending" your wife does. I wonder if that is what is going on with my situation. She says things (that seem a positive step to R or sex), but does the opposite. It's like she is faking the comments and the behavior is the real story. As for something distracting her, it seems just about anything will distract her from discussing or acting on our sex life. I will say that she is a generally distracted person. She often gets distracted by the environment or people around her.

The MC told her that it was perfectly reasonable for me to want to discuss it and there was also a physiological reason behind it. That men that go without sex are by nature more agressive. If she with holds sex, I am more prone to show the agressiveness by wanting to discuss it. Some men show agreesiveness through actions, apparently I show mine with words (asking to discuss).
