This is normal when going dark. You are going to have these days where you want to contact or see the wife. Its natual. I am at week 12 now. And I get the feelings still. She still contacts me every once in awhile. I think as long as the affair is going on the contact will be every few weeks to see if they can drag you back or make sure your not moving on. From what I have read. When the affair breaks or they think you have moved on they will really try to break your resolve. The ones who have been there will need to speak up on that.
