As soon as that happens, he has you. All this is still unconscious in most people. All we know is that we feel weak and when we control others we feel better. What we don't realize is that this sense of feeling better costs the other person. It is their energy we have stolen.
Most people go through their lives in a constant hunt for someone else's energy.
Occasionally it works differently. It makes us feel empowered, but you'll see that this gift doesn't usually last. That's why most relationships eventually turn into power struggles. Humans link up energy and then fight over who is going to control it. And the loser always pays the price.
