What are some of the steps men and women should take to keep a relationship?

Honesty, communication and empathy for your partner will take you a long way. Try not to get comfortable to the point where you stop putting effort into the relationship. Keep yourself healthy and presentable, be creative and unpredictable, go out of your way to make yourself and your partner happy. Expect the same in return. Also, make sure you both have a little bit of independence....your own personal friends, hobbies and activities.
