My ex said we can stay friends because she needs me emotionally. Once she said that she misses. She even asked me how I seemed ok with her dumping me?

We broke up because of a traumatizing incident that occurred to her because i wasn't able to protect her. it's totally my fault. She told me we need to break up because she doesn't believe in people changing so i won't be able to change and become better for her although i know i can change. So basically i dont really know whats on her mind. Does she want me to ask for her back or just move on? I really want her back
