How do I get her back?

She broke up with me 4 weeks ago, and on Wednesday she said that she moved on. She broke up with me because I got a trauma response(abused) over something and it resulted in me denying and lying before telling her the truth. She got a trauma response at the same time during the argument.

I have pleaded and begged, telling her that I am going to change and that I am working on myself. Her last message was that it probably would be best if we didn’t talk anymore. It’s been 6 days without contact and the urge to call and send her a message is there. I want her back and I don’t know what to do anymore. What can I do?
