________, the first time we met, I fell deeply in love with you. I knew that you were the man/woman I wanted to spend the rest of my life with. Every moment we have spent together since that day, my love for you has grown. My heart, my soul and everything that I am belongs to you.
You are the most amazing and perfect man/woman I have ever known. You make me happier than I ever thought possible and I feel truly blessed that you have agreed to be my husband/wife.
So I make these vows to you in the presence of our closest friends and family, so that they may witness the promises I make.
I solemnly vow that I will spend every day doing everything I can to be the husband/wife that you deserve; to support, love and cherish you; through the happiest times, but also through the darkest times. I vow to be your best friend, your closest soulmate and, most of all, your faithful husband/wife.
No matter what life may throw at us, I vow that I will never stop loving you, will never stop caring for you and will never stop trying to be the best husband/wife that I can be.
I love you, ________, with every fibre of my heart.
