It does not sound at all like you fit this description, but I included this here to be complete. This is also part of the job, and my job, along with the nursing staff, is to help calm the patient, ease her anxiety and discomfort, and help her focus enough to deliver the baby. I would strongly suggest that you discuss this with your doctor. If for nothing else, then to get an answer, and to let him know how his behavior made you feel bad at such an important time in your life. It's never wrong to discuss such issues.
Solo doctors are their own boss.
I hope it does not come to this and that you get the answers you need. This is an old, tired cliche that is almost never true. I know I don't. While your doctor's behavior was inexcusable, making assumptions about the reason why is not appropriate. You have suggested the right course, which is to discuss it with him.
