Oh dear,
Sounds like your t is confused, it is no wonder you too are confused with her mixed signals. To me its sounds like she wants to help you but is unsure if she is actually able to help you and is suggesting (nicely) that you do have the right to see another t if things are not working with her. Also it would be remiss of her as your therapist not to let you know you have this option and that if you and her haven't been able to work through your trust issues together, it is likely you will run into the same issues with your new t and repeat the cycle with new t.
