There are no rules as to what you should have in your vows. The main idea is that your vows represent the life commitments you are making to each other. Below are some examples of traditional and non-traditional vows.
Traditional vows
I, (Bride/Groom), take (you/thee) (Groom/Bride), to be my (wife/husband), to have and to hold from this day forward, for better or for worse, for richer, for poorer, in sickness and in health, to love and to cherish; and I promise to be faithful to you until death parts us.
Non-Traditional Vows
I, (Bride's Name), take (you/thee), (Groom's Name),
to be my [opt: lawfully wedded] husband,
secure in the knowledge that you will be my constant friend,
my faithful partner in life, and my one true love.
On this special [opt: and holy] day,
I (affirm/reaffirm/give) to you in the presence of God and (all those in attendance/these witnesses)
my (pledge/sacred promise) to stay by your side as your [opt: faithful] wife
in sickness and in health,
in joy and in sorrow, as well as through the good times and the bad.
I (promise/further promise) to love you without reservation,
comfort you in times of distress, encourage you to achieve (higher/all of your) goals,
laugh with you and cry with you, grow with you in mind and spirit,
always be open and honest with you, and cherish you for as long as we both shall live.
