Based on the research, there are five ways to develop the deep friendship of companionate love that lasts. First, lighten up. Passionate love tends to be heavy—it is usually serious and unfunny. Good companionate love, which leads to rising happiness, is much lighter, because best friends bring out the lighter side in each other. They gently joke with each other and have fun together. Goof around together, like you do with any close friend.
