Here is my take on what has been happening. Obviously this is just a guess. H sees no long term future with OW and could well be happy just to keep her as a " bit on the side" , by moving to Apptmt she may have put pressure on him to be more involved with her now he is away from home. So he is trying to back away a little.
In the end it could be completely different. That is the problem with snooping , you never realy get the full picture. To my mind , you can use it to test honesty but little else.
