Your plans won't change. They'll just have to wait a while longer, until this place is done with you. Then you'll be sent back and you won't remember a damn thing about it.
A while back my son, Stiles, was sent back to our world. He lived out about five years there and then, he got pulled back here. When he was at home he didn't remember anything that happened, but when he got back it all came flooding back.
So, my point, you'll have your wedding. It's still there and will go ahead, should you want it to. Things just got paused a while.
