4) You can make each other happy.
When there’s a deep connection between two people, they each know what the other wants and needs. So ask yourself this question about the person in your life: Do you know what it takes to make him or her happy? Think about minor, moment-by-moment issues, like where that person likes to eat and what kind of back rub he or she enjoys. Additionally, think about larger matters as well: Do you know how to help her relieve stress? Can you get her to talk about her dreams and visions for the future? When she’s struggling at work or with a family issue, can you help her come through the storm and find the sun again? And, just as important, does your partner know how to do this for you as well? If so, that’s another reason to believe that you’ve found “the one.”
