But why if he was with a woman would that automatically open a can of worms?
My husband used to go off to lunches as a part of his business, with both men and women and when I was at work, I had colleagues of both genders that I used to lunch with as well. Now if they are doing "just like the ivy, I'll cling to you" that's something else and in those circs I would be over there like a shot saying how nice it was to see him and that I hadn't seen him for a while although I of course chat to (wife's name) often yadda yadda because i am an evil and vengeful cow. And yes, if she was a close friend, I would tell her, risking opening the can and losing my friend because that is how I would like to be treated. But I repeat, innocent until proven.....
