They say don't shoot the messenger, but nobody warned me the messenger gets buried. Six months ago, I saw my best friend's husband at a hotel in Lekki with a young woman. Not a business meeting — they were checking in together at 10 p.m. on a Friday, holding hands, laughing. I was there for a dinner meeting. I saw them. I took no pictures because I was shaking. This woman has been my friend since university. We braided each other's hair in Queen's College. I was her maid of honor. I held her first baby before she did. So I did what love requires — I told her. Privately. Gently. With evidence of the hotel booking I found online matching his card transactions. She looked at me and said, "You have always been jealous of my marriage. You are single and bitter, and you want to destroy what I have." Then she blocked me on WhatsApp. She told our mutual friends I was "obsessed" with her husband. She posted on Instagram about "fake friends who can't stand your happiness." I am devastated. Not because she didn't believe me — shock makes people denial. But because she chose to destroy my character instead of investigating her husband. Now I hear through the grapevine that he has moved his mistress into their second home in Ibadan. My friend is posting family photos with captions about "Godly marriage." I have learned a bitter lesson: In Nigeria, marriage is a cult. Outsiders who reveal the secrets are burned as witches. The code of silence is stronger than sisterhood. We would rather h@te the truth-teller than face the truth. Have you ever lost a friendship for being honest? Would you tell your friend if you saw their partner cheating, or would you mind your business? Let's discuss the real cost of loyalty.
