Re: Wife wants to go for drinks with another man while I am at work what should I do?
Okay, I'll be the voice of dissension. It's canon around here that men and women are not allowed to have opposite sex friends, but I call bunk on that. That certainly is not the case in my social circles/milieu, and none of my friends would dream of trying to dictate to their spouses which friends were acceptable based on gender.
However, be that as it may, you should be talking to her about this. It clearly bothers you, and you need to communicate that to her clearly. Tread lightly, though --- it is my opinion that being jealous and controlling will do more harm to your relationship than her playing tennis and having a few beers with a friend will.
Also, if she has the sophistication and independence to go to China, she may not take lightly to you trying to control her friends. I certainly wouldn't, but again, I acknowledge that I am in the extreme minority here, and I won't post on this thread again. So put away the flamethrowers, guys, I know you want to blast me, but let's keep focused on our firefighter friend and his question. If she is having an affair, Sui, you'll get good advice here.
