With my approval, my T gave my number to another client of hers who wanted to go into the same business as I. It seemed a little unusual, but I figured it was because it was something I had never done before. But in the end her other client and I have become good business connections for each other.
But maybe the difference is that I didn't hire her for help, we were just resources for each other.
I think it's ok for you to talk about it with your T.
