I tell you, back in the day when I dallied with married me, if the guy's wife had singled me out for chatting, friendship, etc., it would have freaked me out bigtime.
When 2bx was having his EA with mini-me, I used social humiliation as an effective deterrent. My baby sister ran with the same crowd as mini-me but was much more popular so I just asked her to tell all the kids, even the ones who were closer to mini-me, that mini-me was a total loser who flirted with older married men because she couldn't get cute college guys.
