But a few jilted lovers tend to channel their emotions into vengeance.
He found out that his fiancee was cheating on him, and to make things worse, it was with her pregnant sister’s husband.
So he took his revenge by disgracing her on her wedding and the shocking video has gone viral.
But instead of a video montage showing the couple’s journey of love, the projector played a steamy bedroom scene featuring the bride and her brother-in-law.
As the intimate footage plays on a big screen behind them, the guests gasp in horror.
The groom did not stop at humiliating his bride in front of her family and friends, for the footage of the incident soon made its way to Weibo.
Reaction over the groom’s act of revenge has left social media users divided.
Most were on the man’s side, stating the bride “got what she deserved”.
“Best revenge – in front of all their family and friends,” one user commented.
“Honesty, I am this petty and would 1000 percent do this,” another said.
“Man stood there knowing the calamity he’s about to cause,” someone else wrote.
“Isn’t this at the party so doesn’t that mean they already said I do?” one person said.
“Why’d he go through with the wedding?” another asked.
Many tried to explain the move, that it’s very hard to get deposits back from wedding venues once they are booked.
“Maybe he found out too late and the wedding needed to be paid for regardless whether they broke it off,” one reasoned.
“Satisfaction people. Embarrassing her in front of everyone was probably worth it for him,” another stated.
“And SHE’S the one that gets mad at the end?” one person wrote.
“Not her throwing the flowers at him, the audacity,” another said.
Whatever it was, hopefully, it teaches cheaters a lesson about the dangers of having an affair right before getting married.
