younger woman with older man

[Undertoad]

She writes it off as OK because older guy just wants a fling, not a possible serious love/marriage arrangement. She has more in common with your oldest child than with you. She can't possibly imagine being married to someone with kids in high school when she has spent half of her post-adolescent life in high school. She figures that since you're older and wiser you kind of understand all this stuff and there's no need to spell it out, even if you say meaningful relationship-things. She is not old enough not to know when to not play games.
