Financial Generosity

This makes me mad about me. I need to understand why I allow myself to be so financial generous to men, this guy in particular. It seems there is a relationship with wanting to be loved and trying to buy it. No money was stolen from me. He paid for his far share sort of but I make more money. And I was more than willing to spend it on fancy hotels, expensive food & wine etc. Thankfully I did hold back on gifts but certainly bought him more than the ZERO I got in return. Why do we women do this? Remember the old days of chivalry when men paid for everything. Any thoughts?
