Romeo and Juliet: Wedding Vows?

I have an assignment on writting a very short weding vow from each of them; anyone have any ideas at all? It should be attempted to rhyme and Old English type language, if you know what I mean.

May God bless anyone who helps because if not, I am ******* screwed.

Oh and by the way, it can't be the ones from the book, like those really short ones. Something made up. Any idea will help.

Suggestion:

I Lovith thow like a summers day
Even in The middle of May
Your as sweet as can be
A pretty as rose
There's something ill always no
I Love You

Sorry not that good but it might work maybe Haha good luck!!
