Maybe he made a bad choice, maybe you made a not so great choice, there seems to be a lot going on in this situation.

All I can offer is that you owe it to yourself to end therapy in a way that feels right to you. From what you wrote here, you seem to have some regrets about how you left things with your T. You might try and let things settle a little bit, figure out what you want, and then call him back and set up one more visit. You will be able to tell him how his decision hurt you, hear his explanation, and move on from there.

The last time I was in the ... "F this I quite therapy" situation, making that call and going to the [last] session was honestly one of the hardest things I made myself do. But I made it about ME and what I wanted before closing the book on therapy. That session turned out to be a very important session.

I hope you can figure out what you really want, and then have the courage to take steps to get it.
