I'm sorry that I haven't redone my earlier post to you yet.
I agree with SD, that the letter appears to be more a complaint than anything. She already knows you are unhappy.
The theme that I was trying to generate a working example of in my first post to you, was simply, generating a conflict to highlight the need for a decision.
You have decided to work on this issue. You wife has not. There are many reasons that she hasn't, many of them probably legitimate.
What you have to do is pin the issue down.
"Dear wife, I am anxious for your help with our sex life. My concern is that ignoring this issue, is going to tear our marriage apart.
I am asking you to directly address the issues plaguing our sex life by directly working with me on it. I am willing to, go to counseling, seek medical aid, and address any issues with me that are contributing to the state of our marriage.
Please consider this issue. I would like to discuss this with you tomorrow at dinner.
All my love, HDSocal"

I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
