His book, The Five Love Languages, is admittedly full of cheesy truisms (“keep your love tank full”), and it sounds like a bad quiz you’d take in a magazine. This term was coined by longtime relationship counselor Gary Chapman. In fact, it’s one of the simplest ways to improve it. The idea is: we all express and feel love differently, and understanding those differences can seriously help your relationship. That’s sort of the idea behind the concept of love languages: they let you in on what makes your partner tick. Later in a relationship, maybe you’ve wished your partner could read your mind and know what sets you off, and what you respond well to. Over time you learn more and more about them, including their likes, dislikes, and how they think. Getting to know a person in a romantic relationship is a gradual process.
