People confused 'addiction' with 'dependency'. It's natural we come to depend on someone's caring & trustworthiness'. With time and when we have worked through these early stages that for some where never successfully resolved we become interdependent.
I've found going through all these uncomfortable & scary feelings toward another has helped me know who I am and why I was the way I was. Therapy doesn't aim to crush you or keep you 'caged'. It teaches you how to find wings & fly.
