I like the tips given in the article on How to Be a Good Girlfriend.  The reason for this is that they can also be applied in marriage.  All too often I have seen marriages that the couples have lost their own identities.  I think it is very important for each person in the relationship to have their own hobbies and interests.  The advice to "not sweat the small stuff" is a huge piece of advice for a lasting marriage.  I have been married for 21 years and have learned the fine art of not sweating the small stuff.  It is so important to overlook and ignore little things that bug you in a relationship or person.  I have found letting these things slide have made for a much more pleasant atmosphere.  Nagging is a definate downer in either spouse.  I say "Let Go and Let God."  I learned early on that letting God shape my husband's character would be a lot less responsibility on my part. Besides, it leaves more time for you to focus on yourself, something everyone is responsible for!  Yes, it's important to have something you both enjoy doing together.  Spending time together can become a lost art in marriage.  This is especially true after a couple has children.  It is critically important that couples spend time talking and relating to one another on a routine basis. The last suggestion of being supportive of your date's activities also applies in marriage.  Whether it be his hobbies or his career, my husband has always relied on my support.  I have also found if I speak positively of my husband in public, it racks up points with my husband for later!
