“I realized the odds were that I’d be a flavour of the week. I realized
that the possibility of one day being married to this new guy was
completely remote. And then I realized that either way, I come out
ahead.

You see, if I’m just the flavour of the week, then the relationship will
have been meaningless. If I’m just the flavour of the week, what I get
is sex with a guy I’m drooling over, without any baggage.

On the other hand, if, however remote, there is the possibility that I’d
find him an even better guy than my husband (who I do love dearly in
spite of what you think), I could only find this out by going with him
now.

Either way, I’d be better off by following my sex urges over my heart.“
