Dear Prudence,
I recently caught my fiancé and his sister together and broke
up with him. I’d always gotten a strange feeling about their closeness,
but I didn’t believe it until I saw with my own eyes. To my family and
friends, it seems like I woke up one morning and decided not to get
married. Everyone is pushing me to work things out with my fiancé.
Initially, I wanted to keep what I saw between them and me. If I tell
people they have an incestuous relationship, it would probably destroy
their lives. I know they’re barely functioning and terrified I will tell
people about them. I’m worried I will seem spiteful if I tell even a
few trusted loved ones the real reason I called off the wedding. At the
same time, I’m heartbroken too and don’t know how much longer I can
handle lectures about “letting a good man get away.” Should I stay quiet
or speak up?
