Why did your wife opt to end the affair over just getting a divorce. In other words did she stay with you for all the right reasons or all the wrong reasons.
What part of your relationship has improved? And how?
I am sorry in advance but I am going to be real blunt here.
If your wife was having a relationship of a sexual nature with someone else then it is not that she is not sexual. She just does not share this side of herself with you. Do you know why?
I can see a real LD person having a EA but not a PA. Which means something in your relationship triggers her LDness. Have you come any where near figuring out what that might be?
I am by all means a HD person with quirks forced into the life of a LD do to relationship issues. I can see someone like myself having a EA that overflows into a PA if my emotional needs were being fufilled to the point it released my more HD nature. But why would someone who is LD does not like sex walk into a situation of not only having one but two peoples needs to fufill sexually.
I am with HD I don't think this is one you will be able to fix without some outside help that can call BS in a polite way.
