Maybe it was just the official document signing. They could probably still have the big ceremony; some people actually do it that way. Still it would have been nice if they'd told you the truth.

Well my fiancee and i are hiding it as well. They rest of the family wouldn't agree with the type of ceremony we want. As far as they no there is no official date, but we are getting married next month.

That's why to have to account for timezones when traveling. And remember leap years plus daylight savings. And make sure the Bermuda Triangle isn't tailing you.

You mean your brother's wife...

Hey, OP here. I'm a girl, so why FML listed me as a guy...I have no idea. Anyway, I'm here to clear some things up. Why we drove so far to see them was because we're both in college and we don't get to see my parents or each other often. My parents and I went out there to celebrate their engagment because we probably won't be able to see them until maybe July, and they had already been engaged a month before we drove there to buy them dinner in March. It didn't bother us so much that they got married without telling us, it's that they lied and egged us on, and had his wife tell my dad through text. They promised they are going to have a ceremony sometime in the next 5 years, but they asked us not to tell the rest of they family they're already married. So now, we're lying to the rest of our excited, curious family. We weren't there to plan anything, the topic just came up during dinner, since well, we were celebrating an engagement. We figured they married for financial aid and tax purposes (given they're both in college and are barely getting by) which is fine by us. They had already been living together for a few years and moved across the state together, so it's not like them eloping was unexpected. We just don't know why they felt they had to lie when they had the chance to discreetly pull one of us to the side and tell us in person the day before. Sorry for the book, but I hope that clears some things up!

In china,lots of poleole had their wedding ceremony monthes or even years later the paper signing

I feel like this would make a great sitcom episode. After you're all done discussing dates and everything, you leave, then as soon as the door shuts behind you: Brother: We forgot to tell them about our WEDDING?! *laugh track* Wife: I KNOW! Brother: How does that even happen?! Wife: I DON'T KNOW! *laugh track* Brother: I am SUCH a bad brother AND son! Wife: You? I'm supposed to be their sister and daughter IN LAW, but not even a year in and I've already something CRIMINALLY stupid! *laugh track* Brother: I can fix this... WE can fix this... Just think. Wife: Okay, I'm thinking! Brother: Me, too.... Baby.... Wife: Yeah? Brother: There's only one way... We have to get married again. *laugh track and applause* *Que wacky, zany episode with all the hijinks you can expect from a bumbling couple trying to plan a fake wedding ceremony ending with the same stresses of a real ceremony finally breaking them down and making them realize that the truth is what all great families are founded on or some other cheesy, canned moral.*

OP, there's absolutely no obligation for you to lie to other relatives. Furthermore, it will destroy the trust between you and said relatives once everybody finds out eventually. Only the couple should bear the consequences of their actions, not y'all, too. It's an unreasonable and very, very selfish request by them.

Your brother and his girlfriend need a reality check in the form of a bitch-slap.
