Emotional happiness

I am reading about neediness and dependence in relationships and was surprised to learn that the most happy relationships are not built on interdependence. In comparison, the happiest ones are whereby the involved parties are usually highly independent of each other. I suppose some of my general unhappiness does stem from being somewhat needy. Not easy for me to admit this as I have a huge ego. Still, I feel a big weight taken off my shoulders by just learning this; you don't need to be with someone to love a person. I have taken back some control now and have started to enjoy my work and activities more. I still love the girl who broke my heart. But it is because from choice, not from need. And I am happy that I have a choice.
