I recognise it from her knowledge of relationships. She is the most knowledgable t I have seen and her understanding makes me feel safe. Also her honesty and transparency, I know that I could trust her to keep my secrets and not to compromise our ratio ship.
I have had a number of dreams about this t where I am upset and she always drops everything to comfort me. I feel held with her.
Also if you don't feel safe why don't you and why stay with a t you don't feel safe with?
I stayed with my ex ts because I was overly attached to them and it wasn't until they showed they were unsafe and I couldn't work with them anymore that I left.
