Ken, I own that book. The introduction of the book Johnson says quite clearly that Hold Me Tight approach does NOT work when an affair is taking place.
Hold Me Tight is a refined approach and will work with MWD appraoch, but the author warns you in the beginning of the text that it will NOT help if an affair is underway.
You should be reading Harley and Tuppy, and others who specialize in infidelity.
THe issue isn't how loving she is twoards you, it is how much access OM has. She and many people in affairs try to play BOTH their LBS AND their affair partner... ask 4luv about that one.. she can confirm this.
Your wife's closeness to you is not an indicator that her affair is over. She needs to learn HONESTY, if she isnt' offering you THAT, then she's still playing you.
