Misty is so right about the wedding--something will go wrong. Do not let it bother you, it will be something to laugh at years down the road. Do not get caught up in all of the trappings of the wedding, focus on the ceremony and the vows you are taking before God.
Married life is not always easy. I agree about picking your fights, some things are just not worth fighting over. Be open to compromise, everything should not be just about what you want or just about what he wants.
Do not go to bed angry--communication is a huge part of having a successful marriage. Do not say things in anger, either. If you are really angry, walk away until you calm down. It is hard to take back words said in anger.
Do little things to let him know you care, I sometimes put a note in my husband's gym bag to tell him that I love him. He goes to the gym before he goes to work--he gets my note after his workout and knows throughout the day that I took a few extra minutes to let him know I love him.
Try to remember each day why you chose to marry your husband. Do not dwell on the negatives, focus on the positives. Do not try to change your husband after you get married....you wouldn't want him to try and change you.
Always put God first.
