AITA for exposing my fiance during our own engagement party because I found out she was still married. My name is Daniel and I am thirty one years old. I met Priya two years ago at a mutual friend wedding. She was charming funny and told me she was divorced for three years. We fell in love fast. I proposed after one year together. Everyone said we moved quickly but I felt certain about her. Her family loved me. My family loved her. Everything seemed perfect. We planned an engagement party at a fancy rooftop venue with almost one hundred guests. Two days before the party my cousin Mira called me in a panic. She said she needed to tell me something important about Priya. I almost did not answer because I was busy with seating charts. Mira told me she saw Priya at the courthouse last month filing paperwork. She said it looked like a marriage license renewal not a divorce filing. I laughed it off and told her she was mistaken. Mira insisted I check the public records myself. That night after Priya fell asleep I searched the county clerk website. My hands were shaking as I typed her name. What I found made my stomach drop. Priya was still legally married to a man named Arjun. There was no divorce decree anywhere. Instead there was a notice of separation filed only one month ago. One month. Not three years like she told me. I felt sick. I wanted to confront her immediately but something told me to wait and gather proof first. I called the courthouse the next morning pretending to be a process server checking a case. The clerk confirmed the marriage was active and the separation filing was recent. I asked who filed it. She said both parties filed jointly after reconciling then splitting again twice in the past year. My entire body went numb. The woman I was about to marry had been going back and forth with her husband while planning a wedding with me. The night of the engagement party arrived. I stood on that rooftop watching Priya laugh with her mother while wearing the ring I saved six months to buy. Guests clinked glasses waiting for our speeches. When it was my turn I took the microphone and thanked everyone for coming. Then I looked at Priya and asked her one simple question in front of everyone. I asked if there was anything she needed to tell me about her marital status. Her face went pale instantly. She stammered and tried to laugh it off saying I was joking. I was not joking. I pulled out the printed court record from my jacket pocket and read the case number aloud. Gasps spread through the crowd. Her mother dropped her wine glass. Priya grabbed my arm begging me to stop and talk privately. I refused. I told everyone that according to public record she was still married to a man named Arjun and the separation was filed only weeks before our engagement announcement. The room went silent except for her sister crying in the corner. Priya finally broke down sobbing that she thought the divorce would be finalized before our wedding date and did not want to worry me with details. She said she truly loved me and the marriage was basically over on paper only. I asked her how many times they reconciled during our relationship. She admitted twice. Twice she went back to her husband while sleeping in my bed and wearing my ring to family dinners. Her father tried to calm the situation saying it was a technicality. I told him lying about an entire marriage is not a technicality. I took back the ring right there in front of everyone and walked out of the party. My phone has not stopped ringing since that night. Her family says I humiliated her publicly and should have discussed it privately first. My own family is split, some say I did the right thing exposing her before signing a marriage license with a woman still legally bound to someone else, others say I should have given her a chance to explain before destroying her reputation in front of one hundred guests. I keep replaying that night wondering if I was too harsh or if she deserved every second of that humiliation after two years of lies. So Reddit, tell me honestly, was I wrong for exposing her like that in public, or did she bring this entirely on herself.
