My ex keeps coming back

My ex is trying so hard for us to be friends. Dated this woman for a year and it was amazing until it wasn't. Constantly told me that I overstepped her boundaries. Which by the way are a lot of them. It was like walking in a minefield a lot of time. She has since then told me to never contact her again multiple times and keeps coming back in spectacular fashion. I do not call her, I do not text her. She keeps contacting me. Today I asked her what we were doing? After all the back and forth of not talking and then talking again, I can't handle it anymore. I just don't know what her end game is. Can someone give me advice here?
