Has your T mentioned or have you thought about trying EMDR therapy? It is really great for trauma, and you don't have to talk about it for it to work. This doesn't necessarily mean you need to quit with your T. I saw an eMDR T while I was seeing previous therapy. I have a feeling talking might hurt you more, or at least the thought of it keeps you paralyzed.

I really don't think attachment or non-attachment has much to do w your ability to talk about the abuse. I mean, it isn't good if you are constantly worried she hates you.

I really like my T, and am allowed out of session contact, but I wouldn't say I am super attached to her either.
