Wedding vows

Hi all! This is my first post so bare with me. I'm getting married this Saturday. were doing our own vows. My fiance is planning to have his vows memorized and he expects me to have them memorized aswell. I told him upfront I dont do well speaking in front of others and that I would forget everything I'd like to say, and he added it would be offensive if I read them, rather than have them memorized. should I read them or memorize them?
