One thing that stands out is that he does not have the responsibilities that you have which makes his life much more foot-loose and fancy-free.

What I mean is that you have the kids, and that is a full time job! Imagine if he had the kids like you do, he certainly would not be able to carry on the way he does.

Lots of these guys want more freedom and so they run away from it for awhile.

I really don't think he is as happy as you think. OW is very young and oh so infatuated with him, his money, and what he has to offer in the area of material things. This too will wear off.

Sure she likes the kids because she does not have them full-time.

Get what I am saying.

My in-laws will not even allow my H into their home while he is commiting adultery.
