Clinging to people

[The Raven]

I am unsure if you can call this an addiction but when one become super depending on a person, or clingy, his own free will is no longer free and he/she will do anything to keep their partner in their life. It is an often phrase people here "I am addicted to you" which can be easily seen as "I can't live without you or spend any time seperated from you". Is this a disorder? Being unable to have your own life even while being in relationship?
