Just here to offer my sympathies and offer a small suggestion. If you don't want to leave, it might be easier to just accept he is what he is and won't change.
That takes away half the battle. Learn to protect yourself from his harmful comments, ignore them if you can and move on with your day.
It would makes things considerably less stressful than battling him over things he doesn't see need to change.

No this isn't what most relationships are like, are you deserving of something better? Absolutely! But if you are to insist n sticking it out, making peace with it might make things a little easier.

I wish you all the best, and Hope you have the strength for all that lies ahead.
Take care.
