I would be careful not to over exert yourself in trying to please her, she might see it as coming off as desperate or like a last ditch attempt, she seems very confused as to what she wants and doing things for her will possibly have the impact of pushing her away. I would be very careful with the financial aspect of it, when they get irrational they use spending and experiences as a way to give them temporary pleasure without regard for long term health of relationship. By what you explain it seems that anything you do will not alter her perception of the situation, she's fighting her inner turmoil and anything you do will be seen as an annoyance.
