Love vs Dependency?

A filmy rosy topic? No it is not. This is the most complicated topic on earth if you ask me.
There is just a thin film between love and dependency. There is no love without dependency , yet ironically it is not love if it is just dependency. I love my parents... I miss them so much , I cannot live without them! Do I love them or am I so dependant on them that I look at them for everything. I'm so close to a dear friend and will have to talk to her everyday. Anything that happens in life - be it a happy or sober incident, I will have to share it with her immediately. Do I love her or am I dependant on her?
The truth is nobody just falls in love with another individual. Probably one might like an individual for what the person is. But love comes up when you feel that the other person is an integral part of your life and life is difficult without the person. This is always associated with an iota of selfishness. Accept, it is dependency - expecting something from the other.
What differentiates real love from dependency is the what you give to the other person and not just expect; how do you react when you don't get what you expect. Do you still love the person ? Yes? Then that is Love!!
Love starts with dependency, but ends soon if it is just dependency ....
