I have experienced the double life weirdness as well. It's hard to shift over, but once you do, it's hard not to relax and enjoy yourself. I look at it as a way to give myself a break from the sitch. Not only that, but I realized how healthy it was for myself. It is something I will continue to do regardless of how things work out with my W. Maybe not as often, for sure, but from time to time.
