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?
