I don't get it- you teold your T the other male T slept with her. Client abuse should be reported She should be on your side.
As to what happened with the first T- well, obviously SHE didn't deal with HER stuff before she became a T.
If I were you (and were it possible) I'd stay from this "agency" as far as possible. Reporting would be a next step but if you don't feel like it, don't. You need to be stronger for that and the only priority now is your mental/physical wellbeing.
