How do you not get offended when a girl thinks she can do better then you?

Like I have been great to this girl never called her names, never physically harmed her. I have always did things that showed how thoughtful I was about her such as letting her use my car when hers broke down when she had to get to work. She has called me all sorts of names, her sister threatened to kill me in my sleep and had borderline personality disorder, she has smacked me in the back of my head twice and has gotten up in my face to provoke a physical confrontation. She has me out to be a horrible person to her friends and family. She actively uses my autism against me saying that if she was dating a normal guy he wouldn’t do repetitive phrases or make weird noises, she also dislikes that I listen to rock music and watch horror movies
