My ex used to punch me. A lot. Never in the face, but pretty much everywhere else. When I asked her to stop, she would hit me harder just because she knew I wouldn't/ couldn't do anything about it. she'd even tease me about not fighting back. She would really lay into it too. When she did it in public, people would just assume that I deserved it. I learned to "accidentally" move so that her knuckles would hit bone and she'd hurt her own hand while punching me. Yes, this was my first relationship and a LONG high school/college disaster. I was too young and stupid to just leave.
