This is a quote from Leap Year but its sweet and meaningful for weddings

"May you never lie, steal or cheat. But if you have to lie then lie with me every night as I sleep. If you have to steal then steal away my sorrow and tears and if you have to cheat then cheat death because I wouldnt want to live a day without you by my side"

And from yours truly

"I reach Heaven when I am right there in your arms"

"Hold me Close, Hold Me Tight
Make my world sweeter and right
Stars May Glitter, Moon May Be Bright
All I Wish is to be Yours Tonight"
