I hate the doctor I work with

So I work at a dental clinic as an assistant and I can't STAND the doctor I work with. He complains about me to my partner, rather than confronting me. My partner said that when I talk to him, that I make things sound complicated, but in all honestly, even the simplest things, he doesn't understand! His English interpreting is off. Not that I have anything against people from different countries, but my lord! I can dumb things way down for him and he just doesn't understand. And then he told her that I never answer him when he asks me questions. I answer him ALL THE TIME! Ever since he got back from India, he's been super picky and just a dickhead in general. Oh, plus he's upset because I never told him I'm pregnant. Excuse me for not wanting to announce it to everyone in the clinic just yet!!
