Can I get her back?

I was with a gorgeous girl for a year and a half. (F22) I’m a male and I’m 27. She lived with me and would hardly go to work at her salon and was kind of lazy. I broke up with her twice and kicked her out the second time in January. We have been talking on and off since and hanging out and even hooked up once in March. I realized I messed up after she finally went to EMT school and now works regularly. She is the most loyal and loving girl. I am trying to get her back and now she said she needs space. When we’d go on dates she told me about the dates she went on and she only hooked up with one of them this year. She’s very honest and upfront. She wants space and we didn’t have any problems except for me. Our relationship was great until I ended it. Thanks for reading and I’m just curious what women think? Can I even get her back at this point? She randomly calls me sometimes and the next day she’s cold to me. I regret ever leaving her and I don’t think she’ll ever believe me again.
