It should be one of the happiest days of people's lives, but for some people their wedding day can turn into one of the worst.
Brides and grooms who have been left at the altar have been sharing their experiences on anonymous messaging app Whisper.
Here are 11 people who have explained what happened to them, what went through their mind and what they did in the aftermath:
I got a note from my fiancé saying how sad he was to do this to me and that I should take my best friend on our honeymoon.
My ex let the wedding go on, called my phone and left a voice message. When I got home all his clothes were gone and I never saw him again... we were together for three years.
In my case, he started behaving differently until I started to question why we were together. Then on the day we would have married, he didn't show up.
My fiancé left me when I was four months pregnant, and two months before our wedding. Today I'm happily dating a wonderful man who treats me and my son vry well.
Mine cheated on me and I lost all my money on the wedding that didn't happen.
My 'fiancé' laughed in my face when the pastor asked if he would take me to be his wife and humiliated me in front of my whole family and his. I'm currently in a custody battle for my son.
My fiancé left me three days before our wedding because he wasn't ready. He married someone else three months later.
My fiancé ran off with someone else one month before our wedding. I was completely blindsided.
My fiancee left me for another woman four years ago today. It still feels like it was yesterday.
Just found out the REAL reason my fiancé left me after 7 years together. His mother gave him an ultimatum... 'your fiancé or your family'.
I was cheated on and dumped before our wedding. We were together for over four years. It's the hardest thing I've ever had to do to survive.
