Can you share a bit more about what you feel his perspective is?
From his behavior in your description, it would seem that he feels hopelessly trapped. He tried to escape via an EA, and tried to escape again via binge drinking. What is it that he's running from?
How long have things been difficult?
Can you remember a time when he was truly happy? What did that look like? What's different now?
What role do you feel you have played in your marriage difficulties?
Have you tried to initiate sex and he has refused, or have you just observed that he hasn't tried to initiate in 13 months? Have you discussed sex, and what does he say?
More details please!
