Search Results: work hard for our money

I've compiled a list of things about someone I've known since I was 16-we only started dating 8 months ago, I need an opinion from all of you about whether these are red flags and if I should stay or run or talk it out?
Thank you

1) He works as a lawyer but I've noticed that he would put the medical profession down- I work as a paediatric nurse and I am in medical school. I noticed he would say things like "the medical profession are crap, useless and lazy" and even though I tell him off and he apologises, he still makes some negative comments...
2) He says he has high standards and wants a girl who can take care of herself "because it saves him from having to do all the rest" Although I look after myself, I notice that whenever I get stressed from university and I need him the most, he withdraws, but when he is having a bad day, I'm always there for him.
3) We met up at a cafe 3 days after Christmas and he appeared angry at me for no reason (to this day I have no idea what I did). I asked him what was wrong, but he dismissed my question and I thought he might have been stressed from work. From the look on his eyes and his face and eyes, I've never felt so scared. It's hard to explain, but I started to have that awful uncomfortable feeling in my stomach. And of course when he saw how scared I was, he accused me of looking confused and then told me it's probably why I "don't have my life together."
4) He asked me one time "so after med school, what are you going to be? A GP or surgeon?" I told him I wanted to be a GP, and he replied "Oh, is that it?"
5) On Christmas day, when my parents invited him over to our house for dinner, he asked me "aren't you going to lose some weight?" My boyfriend is a triathlete whereas I am a marathon runner and swimmer and so I started to feel anxious and insecure about my body.
6) He didn't grow up from money, but ever since he got a job as a senior lawyer in a corporate law firm, he has been showing off.
