Well.... she bailed..............
Then, not to be harsh, but I guess this is your answer.
I understand you don't want to do everything over text, but sometimes, things don't get closure and it's hard but we must do something to bring us our own closure. You can't control other people's actions. To be honest, I'm not surprised she bailed. I think many of us were trying to communicate with you that she doesn't care. I just think you're in a time of your life where you want her to care, and so there's this thing in you that's pushing for another conversation because a part of you wants to be in her life.
Which makes me sad, honestly, because it shows me something in you is hurting and needs validation from anyone you can have a friendship with. Like I said before, you must know your value first in order to know how to be treated like you are valuable. I don't' have anyone like that in my life simply because my value is more important to me than relationships that treat me terrible. All my friends are friend's that are not toxic, but uplifting and who challenge me.
I hope things work out for you!
