There is no wrong way or right decision; only what is most comfortable for you. If speaking aloud during your wedding is an unwanted load of pressure on an already full day, don’t do it.
On the other hand, if you are comfortable reading a vow you’ve written beforehand, here is a sweet template to get you started. Once you’re started, feel free to throw out the template.
Lisa’s throwaway template:
(Name), I love you because. . . .
I love your . . .
I love that you . . .
And how you make me . . .
I promise that . . . .
And I promise to . . . .
A few more thoughts:
At a minimum, try to write five or seven lines.. At maximum, anything longer than a page is a little rough on your guests.
If you are a funny person, it’s OK to add a touch of humor. If you have gone through very difficult circumstances with your beloved, you can mention this, but overall, try to keep everything in the vows positive and upbeat.
Some couples feel better if they know what each other will say, so they write or review their vows together. Others prefer to keep them secret from each other until the ceremony. If you choose the latter, try to let each other know how long your vow will be for a better balance.
It’s best to jot them down. Trying to memorize them adds another element of risk, which might keep you from being fully present during your wedding ceremony.
Finally, don't be afraid to try writing your vows. If they come from your heart, there is no wrong way to write them!
