Chasen,
Having just gotten my PPL and failed my first checkride I will tell you a few things I experienced.
1) When I did not know a question, systems or FAA related, I told him I did not know the answer but could look it up for him. After opening and thumbing through the Operators Manual or FAR to the correct section he told "ok, you know where it is".
2) He did ask me twice if I was "sure" of an answer. Made me rethink, but firmly told him I stood by my answer.
3) I failed my checkride for failing to execute a clearing turn before a stall. His exact words were "you were 100% up until this point". I wanted to open the door and jump. However, I kept my cool, continued the checkride and the following day I returned to perform the clearing turn.
^ This is what you should read.
The longer I do this, the more I think of checkrides as nothing more than just a game between Instructors and DPEs; a dance maybe, he leads and I follow.
Each DPE has a certain rhythm and in the end the instructor starts to move to it. "X" DPE likes to bust students on clearing turns, so we instructors start "coaching" for the checkride.
He's an acceptable pilot but man, he can do clearing turns like a villian
What you wrote reads as if you were simply not "coached" enough to be playing the game.
It shouldn't be a game, but it is (IMO). It stinks.
You also have to remember that he is going to put his name to your certificate, with only meeting you for four hours and flying with you for 1.5. There are a lot of things that might put out a vibe of being in over your head, "uh" might be one example. Something told him to bust you and he went after you until you did (just guessing).

And JEP is 100% correct, your instructor is taking it personally.
Too personally.
That explains his actions.
Don't bail yet. It will be cheaper to finish up there. The instructor at the next school over will want to see you do probably much more than three hours of flight and plenty of review ground to see if you are ready for his sign off.
Money and time says stay put if those are the most important to you.
Cheers.
