It sounds like he's pushing you a little bit - not a bad thing. This has happened in my therapy and I've found it's all part of the process. A client may initially need heavy-duty support and nurturing in order to feel comfortable. As therapy progresses and the client gets stronger, they may need some nudging to get out of their comfort zone and start tackling some difficult things.

Probably your T has always been aware that you shut down when he makes some points, but he accepted that. Now you're stronger and he's being open about this and bringing it to your attention. It stands to reason that this will be difficult, but please don't feel that his frustration (how much is real and how much is perceived?) means that you are somehow not worthy or are screwing up.

The fact that he's pushing a bit means that you've made progress and are stronger and he feels you're ready to hear this.

The reason this seems so obvious to me is that I spent most of my last session discussing "pushing" with T, so it's fresh in my mind. I had no idea that it's done so intentionally and with such surgical precision.

Hang in there - don't turn this into negative thoughts about yourself.
