“I caught my husband-to-be being intimate with my maid of honor (former best friend) on our wedding day. My friends tried to tell me, and I wouldn’t listen. What could either of them say? They were caught. I immediately went to my dad, calmly told him what happened, and then walked down the aisle by myself...and made an announcement to the invited guests that the wedding was off.”

"I called my dad, and I told him I couldn’t marry my fiancé, and he understood. My mom, on the other hand, didn't understand and told my fiancé before I could. He was rightfully very upset, and we didn't end things well. I didn’t talk to my mom for almost an entire year. I do regret how things went down, but I don’t regret the decision to end things. It’s been five years since then, and I’m about to marry the man I developed feelings for, and I’m happier than I’ve ever been."

"I drove straight home to Denver (from California). I only told a few people why I bailed because I was embarrassed and didn't think people would believe me. My friends and family were very upset with me for years. I finally found 'the one,' and everything worked out, but he and his SISTER are still both unmarried and now live together in Oregon. I never did figure out what was really going on with them."

"I called my parents and told them I needed to leave. I packed up while he was at work the next day and left and never looked back. I’ve never regretted my decision for a single day, and now, I feel like my very best self."

"A week after the wedding, he confesses that he was living with the ‘girlfriend from before' and 'living with her convinced me to marry you.' Ten years and three kids later, I divorced him — best decision I ever made."

"Then, I asked them to collect any gifts they brought and take them back as well as to enjoy the reception. Food, drinks, and cake already paid for. I then marched down the aisle and left for a solo honeymoon, which he'd fully paid for. Less than three months later he married her, and after two kids in three years, he left her for another girl."

"I practically had to choose between him and my education and career. I had enough at one point but didn’t want to disappoint my parents, because what would they tell all these guests if the wedding was canceled?! Funny enough, my entire family was relieved when I called it off. A few months later, I heard he got married. Zero regrets."

"After leaving the church, I got into an Uber and took a selfie of myself in my wedding dress, the church growing smaller in the distance as the car drove away. I sent the picture to my ex-fiancé with the caption, 'My life begins today,' then blocked him. #NoRegrets."

"Spent the next six months getting dumped and then getting back together, until I finally stopped fighting to stay together. The way he acted after the fact confirmed my gut feeling that something was off. Not going through with the wedding was the best thing I could've done for myself, but it definitely put me through emotional turmoil for about a year."

"I can't remember anything in particular, but I ended up dating the girl a little after, and wowie zowie... There were issues."

"When she and the groom moved in together, the groom's family bought him this plant as a housewarming gift (he, for some reason, really liked this particular species of plant). His fiancée demanded he get rid of it: "We are starting a life together so everything should be ours; I want all remnants of your former life without me gone.

I think the morning before the wedding, as I'm driving to my hometown, the bride and groom and each one's family got together for breakfast or something. The bride started an argument with the groom's mom, being very very disrespectful. The groom defended his mom, and the bride called off the wedding. This argument was over something stupid, too, nothing at all that should affect a relationship.

The best part was that his groomsmen decided to throw him a re-bachelor's party. They just got completely wasted, had blowup dolls, and random stuff like that. They also ate the top tier of the wedding cake, something that is traditionally reserved for the bride and groom to share. The ex-bride-to-be got super pissed when she saw that on Facebook."

"I cracked, and first cancelled the wedding and eventually broke it off all together. Life can take you in so many directions."

"She ran off with the other guy she was seeing and canceled via phone call. My friend had a fun, pleasant vacation. Oh, and this was apparently the second time this bride called off a wedding."

"If that is the case, where the hell was he when I was dealing with the loss of my mom? Where was he when they took her off life support? Probably still at his parents' house, lying about being employed. Oh, and did I mention we were together for three years and friends longer? But, hey, I dumped him over Facebook since that was the only way he wanted to communicate lately, and then, I got my master's, cut my hair, and lost 30+ pounds on the exercise bike he got me. And since my mom didn’t like him, on her behalf, I unfriend him on her Facebook after she passed. So, yeah, I am doing a lot better without him!"
