I don't know if it would be really productive but I think it would at least be a wake-up call if you said something to her like "What you are expecting from me is unconditional love. Unconditional love is what you should have gotten from your Daddy but didn't. There is nothing I or any other man on this planet can do to make up for that because unconditional love is not the kind of love that two mature adults share."
"Tell me, what is it you plan to do with your one wild and precious life?" - Mary Oliver
