I can see how you are still hoping this reality could truly significantly change for you. I do hope that happens too, but I want to remind you that while deep changes are possible, they take time and hard work, and when they are this serious, they sue to require professional psychological support. then "if" as you said,she comes back to you, and happens to be truly honest, respectful and supportive, then for sure it would be worthy to give her another chance. But just remind yourself that you need to base your decisions on reality, for you to take good care of yourself, otherwise you could easily get back into a codependent circle here you would allow this or other people to use, abuse, neglect or manipulate you.
