I wouldn't worry about how she is going to pay you. That's her problem.
If you wanting her back is that far down the line then just keep detaching and focusing on yourself. Maybe she'll come back if she sees a healthy, attractive individual.
Not worrying, just not understanding her reasoning (or lack thereof).
Just like I don't understand how she can barely stand to ne in the same room with me before, but she's also okay getting in our bed and is almost expecting that I will continue living there after the D.
