I broke up with her, but she won’t come back

Hi everyone,
In short, I was dating my ex for about one year. Here is the timeline of events:
-Initial break up
-6 weeks later, I reached back out to her and we started seeing each other again
-2 weeks later, I told her it wasn’t going to work again
-4 weeks later, I reached back out to her and we started seeing each other…
-one week later, I told her that was it
-3 weeks later, I reached by out to her, but she won’t take me back now..

I know my decisions were completely my fault, which makes it even harder. I obviously regret them, but at the same time, I know I would not feel about her the way I do now if I wouldn’t have broke up with her. Honestly, my perspective is different. I know the reasons I broke up with her won’t be reasons we break up again if we get back together.
Anyway, after I tried to reach out to her again, I made the mistake of begging and pleading with her. I did and said everything I could to show her I changed and that I won’t break up with her again. At first, she said she needed time…I gave her a two weeks and she called. I made another mistake by talking about us. This frustrated her, and she quit answering my calls again. I then asked a mutual friend what she was thinking and this friend asked her directly…she said she need more time and space. however, a week later, my ex sent me a text saying that she doesn’t see a future with me anymore. I have been doing no contact now for 14 days. Looking for some support, and advice. What are the chances she comes back?
