So the cat is out of the bag and we're getting somewhere at last. Yeah! Its wonderful that your W doesn't really have a desire problem. It really is. So the problem is with communication and you are now left wondering I have tried everything, what else can I do? Well, being more like you, my first thought would be oh come off it, lets just do it and the more we do, the easier it gets and the problem is solved, simple as that. Of course its not as simple as that in your wife's case.
We all know that you've tried really hard so how about just telling your W. "I've tried really, really hard to try and solve this area in our M but nothing that I've been doing seems to be working. Obviously I am doing the wrong things. I can't do this on my own. I need your help. Please tell me VERY SPECIFIALLY what you need from me in order to let go of your resentment. I know that when we get into the sex argument, I turn into a monster and I don't want that monster to cause you to have anxiety attacks, so please lets work on this together because I think its beggining to seep into other areas of our M." Hope this helps some Sooner and good luck to you as always. I know you have the patience and what it takes to get you and your W through this.
