In earlier post you said that she's confused and needs time to clear her mind... she probably does. It's her journey and no one can make her do anything, she has to come out of it herself. Asking 'why' now when she is so confused won't give you answers, if anything it might drive her away I guess.
Is it a bad thing to tell those who ask you that honestly you don't know what's going on?
Come to think of it, for me being far from family was more or less an excuse with how I felt about my H. If we were getting along really well, I wouldn't have made the distance the biggest issue. So I suspect she hasn't been happy for a while and she may have been trying to let you know.
But for now try not to dig into it too much, you won't find the answer so soon especially while you are still very emotional. It will take lots of time for her to come through and she may never do so, we don't know. I know you love her very much but like someone said, if you keep letting her know that you will do anything/ be waiting forever, you might lose her.
I don't know why she calls you every week while she says she's gone forever, it seems like she's checking in on you that you are still hanging around for her?
