This is a short message from my girlfriend. Can I have her back?

Being able to make a girl talk like this means that you really hurt her; Since she can tell you this, it also shows that she is actually reluctant to part with this feeling, but your practice makes her unable to convince herself to accept being with you again; If you really like her, start from where you have conflicts, solve your direct contradictions, and reassure her that you can't do this anymore. If you make up, you must be nice to her. But if you can't, you'd better stay away from her.
