i actually have 2 friends in the same situation. lol.

Double wedding...? :)

so... you're marrying your step brother? x] sorry had to do it. But to the OP: It's okay, you were engaged first. And they didn't tell you. So really, it's their fault. Anyway, you aren't blood related so it's fine :)

At least you won't have to worry about whether you should call your fiance's mother "Mom" or not :P

That SUCKS.

You didn't mention disliking your fiance's mom, so I guess you two get along. So, if they end up together, you don't have to worry about your dad marrying someone you can't stand. Also, it's respectful and mature of your respective parents to date awhile and make sure they had a pretty solid relationship before sharing it, since they probably anticipated that it would make you feel awkward. So yeah, a little unusual, but if you like the mom, the good definitely outweighs the bad.

Well personally, I think it'll be a cute story to tell. Definitely not an FML. Be happy for them!

it doesn't make you siblings... just so u know.. not like your kids will come out all weird cuz your parents marry.... although they may come out weird if u aren't bright enuf to know this

this has dan and serena from gossip girl written all over it :P

no freak. its weird and gross. and OP, just make sure you get married before them, so then they'll be the ones having to tell the story, not you. it also has fresh prince of bel-air written on it.
