Don't you think, though, from his perspective, that this is exactly what did kind of happen over the course of the relationship? I mean, I can't accuse you of theoretically never being satisfied. I guess what I'm getting at is there would be something you felt you needed, he wouldn't be too terribly enthused, but would wind up providing it. Take the stone, for example (I can think of others that I interpret as caring - that is just one).

It sounded like he started getting a bit fed up with feeling like he needed to prove he cared beyond what he had already done, to be completely honest, so he started getting a bit resistant when called on to prove himself - see the whole episode where he refused to stand on command. I think his pulling back (and probably other behavior from him around that time apart from not standing) was triggering to you and caused you to escalate your demands that he prove he cared and that this proof be exhibited in the specific way you wanted (otherwise it meant he didn't care).

Hence also his reasoning that you'll either hit up against a boundary or get enmeshed with future therapists.

Sounds like he was terribly frustrated in your last session at least and it's hard for me to believe that happened all of a sudden - so I blame him for not figuring out what to do about it before things came to a head. I don't know what to make of him telling you not to talk to other therapists about him, but I don't like it. Based on your reports, I don't know why he would have said such a thing. I suspect now that your relationship has devolved and he feels victimized by you, he is perhaps looking back at the discussions you two had about ex MC and is fearful that a future therapist will judge him the same way he came to judge ex MC. After all, he won't be there to defend himself and he seems to acknowledge on some level a belief of his that you are manipulative. Regardless, his advice on that doesn't make him look good and I don't care for his shaming remark about the time you spent talking about ex-MC. He might have a point, but if he was trying to be helpful, he would have brought it up at the time rather than when he has ulterior motives.
