If she's still feeling that the argument is unresolved, and if she's feeling accepted and more independent in her new living situation, then I can see that as being more attractive for her than coming home. (Hint: She's 17!)
As heart-rending as this is for you, keep in mind it really isn't all about you. Your daughter is reaching into her future, which means she's breaking away from your control. And it's really, really common for kids who are reaching the age of emancipation to find fault with their parents and their home life. It's part of what allows them to break away.
My daughter, just after high school, moved in with my sister and her partner for a few months. It was a wonderful experience for her, in which she had to get a job, pay rent and learn about the obligations and costs of being independent, all while being overseen by a caring relative. From there, she went on to college. All of this gave her a new appreciation of her life with me and her stepdad. When I saw that her primary need was to be independent, I was actually happy that this "halfway house" situation was available to her.
Your daughter knows you love her and are concerned for her. That may be the only thing she really needs from you at this moment. You raised her, taught her everything you know about life, in preparation for the moment she'd fly away. Some kids do this early, some stick around into their 20's. Both approaches are hard on their parent in one way or another. It's hard to get away from the inevitable pains of launching our kids.
If I were you, I would just let her know you love her dearly, want her happiness and success, and are willing to support her in whatever way she finds most positive.
