With a married man, the girls are going for just a short fling/1 nite stand.
If single, maybe the girls tend to look at the man in a
serious-relationship kind of way? Just my hantam guess.
yeah, the article also said something like that
"Because for some single women, a
relationship with a man who is married gives you breathing room.
You are not accountable to him if you want to see a male friend or
past lover."
