Boundary crossing questions would be like asking your T really personal-type questions about them.....but you are asking here about asking questions about you and your therapy and how your T is doing therapy withyou, what your T thinks about you in relation to your therapy and these are good, non-boundary crossing questions. If your T feels like you have asked a boundary-crossing question about her or her feelings, probably she's going to tell you she can't answer that question.....
