SteveR, I was an altar boy back in the day (Episcopalian, so no Catholic priest jokes, and yeah, I was also a Boy Scout...man, what happened?). Any way, I may be a bit rusty, but I served at a few weddings and I've been to a few at churches of other denominations. Since you're getting married, I feel it's only fair to point out to you that some of the traditional vows include the phrase "foresaking all others".
I'm afraid you're going to have to give her up when you get married.
