When someone is good looking, friendly and likes to have a good time, there's a better than even chance that they're eventually going to get hit on by a coworker, customer, vendor, somebody at a bar, etc. when their spouse isn't around. I am not particularly handsome, especially now that I'm old. However, there have been a handful of women at work over the years who made it very clear to me that they wanted to hook up.
I had worked with all of these women for a long time, and I don't think they were bad people. They had just temporarily lost their moral compass for some reason. It could have been mommy/daddy issues, low self-esteem, a rough patch in their marriage, or what? I don't know, and I didn't stick around to ask.
I've been married for 25 years, and I can't tell you how awesome it is... most of the time. I love my wife more today than I ever did, and that's a pretty damn good feeling. However, we've had our ups/downs and major arguments like everyone else.
We are all human; therefore, no one is 100% trustworthy 100% of the time. If one of those women had propositioned me when I was going through one of 3-4 major arguments I've had with my wife over the last 2 1/2 decades, and if it happened on a night when I was drinking, and if we were in a private setting... Well, I hate to say it, but there would have been a damn good chance that I would be divorced today or having to live with the guilt of being a cheating POS.
Now, I am certain that my wife has been hit on a lot more than me. I trust her, but I also know that she's human, too. If one of her "friends" at work tried to get cozy with her during a time when we were pissed off at each other, and when she was drinking, and when they were in a private setting, I don't think she's any more capable than I am of not acting on her urge to feel good now and worry about regret later.
