My T told me that the point of working towards an earned secure attachment is not that as soon as you get it, you give it up. The attachment relationship was never supposed to be the focus. It was supposed to be the utterly taken for granted background for us growing and exploring and risking and learning. Because we didn't have that, we have become acutely aware of the relationship. So the point of forming a secure relationship is to enable you to do what you need to do. Process trauma, Heal more from your ED, continue to learn what it is like to be in a long term intimate relationship. Even after they've healed a lot of people continue to go to therapy because they see growth as integral to being alive and therapy is a aid in continuing to grow.
It's ok to sense a lessening of your dependence, that is one of the goals of depth therapy (and parenting
) But that doesn't necessarily mean it's time to leave, it's just a good sign you're growing.
