Hey Michelle, I understand the curiosity...as you can see from what I posted on my thread!
The things that you do should be for yourself whether he knows about it or not. If he knows then great, if not then you are better for doing those things for yourself.
Your H sounds a lot like mine when it comes to the "happiness" thing. My H is always grasping for the next thing that will make him happy whether it be a video game, a car, a house...or OW. My guess is the new will wear off and he will see that she doesn't make him happy either.
