Would it help to send him an email? I know he doesn’t typically respond (at least I think you’ve said that) but I find I can articulate intense feelings much better in writing. I think he needs to know exactly how he’s made you feel. Plus, even if you don’t usually email him, I think the rules have just changed and you should feel free to express yourself any way that you need to in the next few weeks. I think you should say some of the things you’ve said here because they are legitimate reasons to feel upset.
