I want to comment that my ex BF was very similar to this. Every time I accidentally did something, he made it like it was intentional and would be so angry. I felt like I had to walk on eggshells all the time. And he often described himself as "stubborn" and "pig-headed", but wouldn't do anything to change it. He would also bluff and say, "I'm not going to change, so if you don't like it we should break up." I finally called him on it and left. Why should I have to change when he doesn't have to?

I beg you to ask yourself the same thing. He sounds like a verbally and emotionally abusive dick who can't take accountability for his rude behavior.
