My tution teacher quit teaching me because I want to take arts after 10th

I have a maths and science home tutor. He's the only teacher that was able to bring my marks in maths from 3/30 in ut2 to 50% in half yearlys in the span of a month.

Yesterday while studying he asked me "app bhi apni mummy ke tarah doctor bano ge na?" I said no because as someone who has grew up around docters, their lives are so miserable. He said "apko engineer ya doctor banna chahiye". I said I wanted to do arts [I want to do psychology because I find it very interesting + they also earn a lot and i also want to make concept art for triple A game studios and at some point create my own indie game studio. I also want to keep editing for youtubers (I've edited for a few in after effects and premiere pro) and I don't think I'd have the time to do that if I take science]

He replied "arts gaande logo ke liye hota hai" aur mujhe apna potential waste nahi karna chahiye.

Now today he tells my mom he no longer wants to take my classes because "I don't want to study" and "i argue with him".

Now my mom wants me to call him and to say sorry just for sharing my opinion? Why do I keep accidentally offending people man 😭
