I just can't put my life on hold for her to the extend that she did for me.
As long as you're there and you have your own ambivalence, would it kill you to try? Not put your life on hold but, support her in this venture? See where that leads you?
I'm assuming the D is on the back burner. Why not try. You can always file yourself or change the arrangement. I don't think it matters that you have your expectations...somewhere you know she deserves some support. If it sucks too much, you can change it at anytime.
