I've been with my husband 30+ years and I would share the following. Be kind to each other. Help each other be the best versions of themselves you can. Don't talk about your personal life to others (especially your sex life)! Only seek advice from those who can keep a secret and who have healthy relationships themselves. Have your own interests as well as interests together. Don't get into competition with your spouse (in any area). Be worthy of Trust & Loyalty. Be unselfish but don't be a doormat - make sure your needs are equally as important as his in the marriage. Work out how to talk through problems. make sure you have the same attitude to money - otherwise you will spend your time together resentful and angry. Think of yourselves as best friends and A Team - and work together towards joint goals. PS Before you get married, make sure you want the same things (i.e. don't do what a friend of mine did and not discuss having children, only to find out, on her honeymoon, that her husband didn't want them). Whew - I think I'll stop now!
