First I have to say it was so brave of you to go in there and say all you did to him. That took a lot of courage. I wasn't in the room with you but from the way you described his reaction, he sounded empathic. He didn't get defensive (good sign), he apologized (good sign), he offered to extend your session (that was nice) and he texted you soon after to let you know your appointment was still available.
What I have found with my T is that the more open I've been about the things that hurt me, the more sensitive he is. I know at some point I'm going to have to accept that I might be overreacting to certain situations but in the meantime, he IS helping me feel more entitled to my feelings. Which is a good thing. Which is how I'm going to protect myself.
And, so, it sounds like it's worth a shot. Maybe he is someone you can build a trusting relationship with?
