Hi Nightsky,
I totally understand about wanting comfort for you and your child part, while also learning to take care of yourself. With last t, I got a lot of that, comforting and safety for the child part of me. It was so healing!
I don't know the whole situation, but I know you've worked really hard with this t to feel safe again after this thing with the client. I think you should trust yourself on whatever you decide to do. Taking a short break, (and I can totally understand how two weeks with no contact would be a break for you) and maybe looking into other therapists, just seeing how it feels to be without t and then reevaluating sounds like a good plan. You can always change your mind along the way.
One thing possibly in favor of finding a new t: you've been with this one so long, and had such a difficult history, maybe new eyes on your situation would help? I don't know. I guess you'll find that out if you call other ts.
Please let us know how it goes.
