Wow... that is quite awful for your wife's friend to be dating someone that is half her age. But, on the other hand, it is not your wife who is doing that. Understandably you are concerned that your wife sees nothing wrong with her friend doing that. I'm not sure if I would say anything to your wife at this point, since she has not done anything.

As for your GAL's... keep at it, that is mostly for your own benefit, and you need to do whatever it takes right now to keep yourself busy, and keep that PMA.
