We made up our own based on our feelings for each other. No canned version or script was used. Like Rhabbi said it was like a wedding ceremony and we just said what we felt; expressing the love we felt for each other was of utmost importance to us.

Sorry I know this doesn't really help you but maybe it will give you an idea on how to come up with what you want to say. Imagine your feelings for the person you will be collared to, what you want to say to them, and go from there.
