I think having your wedding on someone's birthday shouldn't be too much of a problem (my parents had their wedding on my uncle's birthday) but they should have asked and not announced it.

That just screams bitch... I say you go to the ceremony and bring a birthday hat and a wrapped present and as she's walking down the aisle start tearing open the present leaving the wrapping paper right in the middle of the aisle. Would serve her right for knowingly ruining your birthday.

Put candles on her wedding cake and blow them out while having everyone sing to you.

What a selfish bitch!!

That's awful. She's an attention hog, isn't she? I hope you have a rocking birthday!

Screw them in a toast to them I would mention my birthday ! Birthdays are sacred dude- they will forever cast your day of birth in the background over their anniversary.

OP, if I was you, I'd give that bitch hell. Make her attention-seeking ass sorry, that she was trying to take away YOUR day. (Ruin her wedding! Fight fire with fire. )

Id ruin her wedding. Very badly yet subtly. Then again I'm a bitch. She did it on purpose. Now all your b days will also be ruined by their anniversary. Ruin everything and don't attend

that's code for have the biggest birthday party ever

What a control freak bitch. It's just the beginning.
