5. You want to share every experience with him
When you envision your future, he has a major role in it (and vice versa). The idea of spending the rest of your life with him doesn’t scare you. Being by his side is where you feel most comfortable.
When something funny happens or you receive good news, you immediately want to share it with him first. When a cheesy love song comes through your headphones, you instinctively think of him.
From what he ate for lunch to what he’s currently watching on television, you’re interested in all that he does. And, while you sometimes hate to admit this, you’re more inclined to do something if he’s part of it. That’s just what companionship is to you.
