Sorry man,
That is kind of rough. No one wants to feel like a charity case...kind of freakish on her part.
A couple of pointers:
1) If a girl wants to pay for her 1/2 of the meal, and you don't let her, she may interpret that as you are conservative (not as in old-fashioned gentleman, but as in like you will be asking where your Turkey Pot Pie is someday when she is Mrs. EdwardC and you come charging in from work).
I always offer to pay and if she insists, I gratiutiously accept, but then counter with drinks/dessert on me, etc.
2) People love honesty, and they also like stability. Sometimes honest emotions of the strong variety early on in a relationship (e.g. 1st date!) can be interpreted as instability. Just something to think about.
Good luck next time!
