Wedding Guests Reveal the Biggest Red Flags That a Marriage Will Not Last

Wedding guests on Reddit have opened up about the exact moments they realized a newlywed couple probably wouldn’t go the distance.

The stories followed a discussion on r/AskReddit that asked users, “As a wedding guest, what was the ‘this marriage isn’t going to last long’ moment?” One response drew particular attention because of how fast everything appeared to unravel.

Among the most frequently mentioned red flags was a groom who was too drunk to make it through his own wedding day without causing a scene.

One guest said a groom ‘showed up drunk and kept cracking jokes during the ceremony’, to the point that the registrar had to pause the service twice and tell him to take it seriously.

Later, the same commenter said the bride was seen in the kitchen, still wearing her dress, preparing sandwiches for guests while the groom stayed at the bar drinking with his friends.

Things only got worse when it came time to cut the cake, with the groom allegedly ‘swinging the knife around pretending he was Rambo’ as the bride tried to smile through the embarrassment.

According to the guest, the marriage survived only a few weeks.

Another Reddit user described a similar wedding disaster, saying the ceremony had to be held up while groomsmen ‘desperately tried to sober up the groom’ and the bride argued with her father over whether the wedding should be canceled entirely.

Many of the other submissions focused on moments that were awkward, bizarre, or unintentionally hilarious.

One person remembered a groom attempting to include his ventriloquist dummy in the vows, only for the bride to cut in and say, ‘No, we talked about this. I will walk out’. That marriage reportedly ended after three months.

Another guest said a groom ditched the planned first-dance song and instead chose Morrissey’s You’re The One For Me, Fatty, before leaving his bride on the dance floor and running around the room laughing.

Elsewhere in the thread, one bride was said to have vowed ‘in richer and richer’, apparently unwilling to even imagine tougher times, while another wedding started 30 minutes late because the bride refused to come out of the bathroom after deciding the clock hands ‘pointing upward’ meant bad luck.

One maid of honor reportedly spent her entire speech listing all of the bride’s former boyfriends in the order she had dated them.

The kinds of warning signs being shared online also line up with what some wedding professionals say they have seen in real life.

Relationship experts often say the most worrying signs are not theatrical stunts, but the quieter patterns underneath them: disrespect, stonewalling, financial secrecy, and the inability to handle stress as a team. In that sense, a chaotic wedding can sometimes be less important than what it reveals about how the couple communicates when things go wrong.

In comments to Insider, photographer Nina Larsen Reed explained that the most revealing factor is often not whether the day goes perfectly, but how the couple reacts when things go wrong.

“I think that the biggest sign for whether a couple will last or not is how they handle problems together,” Reed said, noting that couples who ‘laugh it off and stay calm’ tend to fare far better than those who spiral into blame, a pattern that lines up neatly with guests’ accounts of chaotic, alcohol-fueled receptions.

Alcohol-related behavior was far from the only issue people raised.

One user described a reception where a bride arranged a dramatic stunt involving the couple’s dog trainer. During the first dance, a fake ex was introduced into the scene, and the pair’s Rottweiler then tackled the supposed ‘intruder’. Even with that chaos, the marriage reportedly lasted about two years.

Wedding planner Lynne Goldberg said warning signs can emerge well before the ceremony, especially when one partner wants vendors to conceal the true cost of the wedding from the other.

“If there are secrets about money going into the marriage, there is a good chance there will be secrets during the marriage,” Goldberg said.

Photographer Jimmy Chan of Pixelicious also said a lack of engagement during the planning process can be telling, particularly when one partner routinely skips consultations. By contrast, couples who last are often the ones who consistently show up for one another from the beginning.

That broader lesson fits what marriage researchers and therapists have long emphasized: the biggest predictors of trouble are usually not one embarrassing moment, but repeated patterns of conflict, avoidance, or contempt. Recent U.S. data also show that marriage remains common, with divorce rates continuing to be tracked nationally and varying by state, underscoring that a wedding-day disaster is not destiny, but it can be a very loud warning sign.
