Staying on the topic, I do believe we can be addicted to that special someone, to show this I found an article that describes the addiction of love. In the article the author says "when we are in love, we feel an overwhelmingly strong attraction to another person—one that is persistent, urgent, and hard to ignore."( Earp, Brain)  Another example is  “By nature we are all addicted to love ... meaning we want it, seek it and have a hard time not thinking about it. We need attachment to survive and we instinctively seek connection, especially romantic connection. [But]  there  is  nothing  dysfunctional  about  wanting     love.”  – Smith, quoted in Berry (2013)   So may be  being  in love  is  something  we must  have  in  our  lives,  and is something  we  can become  addicted to,  which may  explain  why  even  after we  have  a  heartbreak  we continue  to seek  for someone  to love,  and this may not be  such a bad  thing, because love can be something indescribable and truly amazing.
