Many couples choose to write their own vows these days and that can be a wonderful thing to do. It is very touching to hear the bride and groom share with each other how much they love their future partner and how they choose to stand with them for the rest of their lives. Those vows are very important and shouldn't be taken lightly. A vow is a sacred promise and is not meant to be broken.
Back when all couples recited the same traditional vows you would hear "cherish and honour" mentioned at every ceremony. The word honour is crucial to the health of the marriage. One of your top priorities is to honour your spouse. You don't need to agree on everything or have the same interests but you should always honour your mate. Don't let this part of your relationship suffer. Remind yourself how lucky you are to have such a supportive and loving partner and do your absolute best to show him/her the honour every day that you are together.
