How do I make my wife feel loved and secure?

Communication is key but it's important to recognize that communication doesn't necessarily require talking. It's a good idea to have a discussion with your partner to find out how they like to express and receive love (this is related to the concept of “love languages”). This is valuable since you'll have a better idea of how to communicate and show her you care about her. Once you know how your wife experiences love, capitalize on that knowledge. It also helps if you get creative and think a little outside of the box. The element of surprise can go a long way.
