Hi Blessedinthe603,
You may be missing the idea of her, or you may be lonely, as you stated she was your best friend, and you are missing that aspect. As far as a romantic relationship, I don’t see things changing. You can’t fix her, only she can do this. You can get back with her over and over again out of missing her, but it would only prolong things, because it would not make her change, and you would end up where you started, frustrated and resentful.
Maybe after some time passes, you can have a friendship with her, but I don’t think she is ready to be in a committed long term relationship without quality therapy as there are definitely some issues she needs to resolve. If she is not happy with herself or her life, she will make blame others and make them miserable and this needs to be explored in therapy, mood disorder.
