It sounds like an observation, not a a boundary crossing. My T has said he knows I consider him my rock, which for me is extremely accurate and to me very intimate really, probably moreso than that I love him. It is an observation, a very accurate one that he has come to by learning who I am over time. But I don't feel like he's telling me to do anything. I don't feel like he's saying anything that isn't spot on.

Do you feel this is maybe a boundary crossing because you have felt that way in the past with this T because of other situations you mentioned? If so, are they all connected in some way, or are you reacting uncertainly in this instance because the other incidents have confused you?

Perhaps you really need to have this discussion with your T. Your uncertainty about it may have more to do with your past than your T which would be entirely common. Either way, sounds like an opportunity for a learning moment.
