Here's some more stuff to think about:
All behaviour has dividends or "payoffs". Maybe on a subconscious level you like your work because of the attention from beautiful younger women that comes as part of the package, and you justify it on a rational level by saying "I can't earn as much money and have the lifestyle that I now enjoy if I took another job." That may be true, but another job also might not come with the perk of the beautiful younger women fawning over you. In addition, subconsciously you may feel kind of insecure about yourself and/or your relationship with your wife, so that you "need" the attention from the beautiful younger women with whom you work in order to stem some of that subconscious level insecurity. It also gives you a powerful message to flaunt (again subconsciously) to your wife: "Hey, I'm surrounded by gorgeous women at work all day and I could have my pick of them if I wanted... and don't you forget it!!"
Who wouldn't feel threatened knowing that their spouse was in a position to abandon them in favor of one (or more) of a selection of gorgeous specimens of the opposite sex, and that their spouse was carrying on in a way that seemingly threatened to follow through?
If your wife really and truly felt that she was THE number one, most important thing in your life, and that the girls you worked with weren't being used as emotional pawns against her to threaten her position, you'd probably find that her feelings of jealousy would evaporate.
On the flip side, did you ever stop to consider that perhaps the girls from work are nothing more than gold-diggers? They see the material things you have and that you have provided for your wife - a nice big house, a car, a nice lifestyle - and are actually jealous of HER and what she has?
The other thing you need to be really careful about is that you do NOT want to get branded as a man who sexually harasses the women he works with. All it takes is for one of these girls to get her nose out of joint, and they will ALL have you for lunch. Is it worth ruining your career and risking your livelihood for a romp with a gorgeous young thing?
