Albee... long time ago, i did something similar too.
It is not dumb, but we should be thinking more, and fending more for ourselves.
My then husband, now my ex, well he also has a terrible weakness for pretty women and he is never afraid to show them his fondness/attention.
Years ago we went on holiday in Spain, there was a pretty Singaporean girl in our tour group, and he started talking to her before the tour, and eventually when we were in Spain, he found ways to chat with her. He was taking lots of photos for her, even with me around, he didn't stop. (That time we both have our own SLR camera) And silly me, wanted to act magnanimous, even went to lengths to get to know her, and chat with her, finding out information about her to share with him. And during the last few days, i managed to tag both of us on her trip out to another city, and before returning back to spore, i even gotten her mobile number and email address so that WE (actually HE) can stay in contact.
Years later, when i was going through my ex's emails for evidences of his adultery, i came across some emails he wrote to her, proclaiming that he missed her, and his praises of how beautiful she is... the girl wrote back teasing him:"be careful your wife will be angry", he wrote: "don't worry wifey will understand why a beautiful girl like you is unforgettable..."
I felt like a complete idiot when i saw those correspondences between them...
Just a word of caution, sometimes maybe we have to step in to draw the perimeters, cos if you stay silent, he will take it as a consent... know what i mean?
My marriage fell apart, i guess part of the reason is i haven't been firm enough to put my feet down when it is needed.
Stop consoling those women... they don't deserve your time, take care of yourself first. Why must you be doing the dirty job (counselling the girls) while your husband enjoys all the frivolous attention from them??
