i dont think it is a "boundary" in the sense that T is trying to push you away... i thinkhe is doing it so that he (and you!) can focus on you. boundaries aren't all about Ts pulling back. (pls dont point out that i can give better advice to others than myself).
im glad this will be addressed tomorrow. i think needs to tell you one thing, even if he doesn't tell you if he is ok or not: that regardless of his condition, he is still capable of looking after you. if this turns out to be something bad, he can still look after you within that constraint, even if it means helping you process it. he won't abandon you and he has still has you in mind.
