My question reading this statement and thinking about many of your other posts is are her boundaries flexible or inconsistent?

In this entire thread it also seems to me that you are conjecturing a lot based on no information from her (hmm, I know all about this...). For example: "Maybe T realizes that and that's why she's flexible with me. She once told me she is very clinical with some clients, she can do either." It seems that you all do need to have a boundary talk, which I know you wrote early this morning that you wanted to steer away from. But you also said that you'll deal with this when it comes up. Is it coming up today?
