A woman is raging after her husband's "inconsiderate" niece planned a destination wedding, then got married a month early without telling them.

The bride, "Jennifer," announced her engagement 14 months prior to the wedding, and asked guests to make travel arrangements for the ceremony.

Months later, the bride and groom sent out cards stressing "the importance of booking everything ASAP."

"Then, about a month before the scheduled wedding, the father of the bride mentioned, in a VERY offhand manner, that Jennifer had gotten married during the previous weekend, albeit in a new destination and with a very scaled-down number of guests present," the woman wrote on Reddit.

She and her husband were shocked as they had already made plans to attend the wedding.

"Until this point, we had never been apprised of any new developments or changes to the original plans! No card, no email, NOTHING! And because we only learned the news after the fact, it was too late to cancel our reservations and/or change our flight," the frustrated woman recalled, adding: "Consequently, we were out quite a bit of money!"

Still, the woman tried to sympathize with her husband's niece.

“The thing is, I understand that that life happens, and sometimes plans change. In this case, Jennifer and her beau actually had a valid reason (it’s a long story) for doing what they did. But I DON’T understand why we weren’t told about the change in plans before the actual new wedding took place," she wrote, noting the couple could have at least let them "and the other dis-invited know via a mass email."

"Breach of etiquette, inconsiderate, and yes, tacky!" she concluded her post.

Users in the comments blasted the bride and groom for poor etiquette.

"Yeeesh, what would have happened if you hadn't run into her dad? Or if he hadn't bothered to mention it? I wonder if there are still guests planning to go with no idea that the wedding is off now?" one user asked.

"That is absurd. They should be compensating their guests. I can't imagine doing something so incredibly rude and selfish," another wrote.

"Since the trip is non-refundable, just go for vacation. It'll probably be more fun without the wedding BS," someone else suggested.
