I am trying to get better at dating my husband. We started dating after High School, so there were plenty of events and things already planned for us to do. We got married, and have kids now. We also enjoy relaxing at home, so we sometimes forget to set aside specific times to nurture our relationship. Thankfully we can still do this at home, going out does not a date make! This week we made dinner, had someone play with our son and sat around making treats for Halloween. What made this date different is that I had a specific topic that I wanted to discuss with him. We talked about traditions in our families and what we wanted to do with our kids to build a family culture. It was fun to set goals together as a couple, and we did something we both enjoyed at the same time. It doesn't have to be big or costly, but it does need to be thought out. You don't go in to a job, or test with out some idea of how things are going to pan out. A date should require just as much if not more planning. Especially since your marriage should be your number one priority. Treat it like you care! 
I came across an article about the ten things happily married couples do, from the January 2012 Ensign.

1. Have positive conversations
2. show affection 
3. Remember that you are each others therapist
4. Be humble and cultivate Christ like attributes
5.Date Frequently
6.Enrich your intimacy 
7. spend time with children
8.seek feedback and help each other
9.eliminate anger
10. Be aware of the others stress level.

This list is important no matter how long you have been married, and I believe dating frequently, which means once a week, can help cultivate all of these in your marriage. If you are having fun together and talking to each other about your goals you'll improve in every aspect of your marriage.
