AIO because I asked to split the bill at an expensive restaurant that SHE picked?

I have been seeing this girl for about a month. I have spent maybe $400 on various food and drinks, plus presents for Christmas (she got me nothing). I have gone to her house to cook twice and she offered 0 help both times. I have dated maybe over 30 girls in the past 10 years and have never had a girl not at least offer to cover part of some expenses. It’s more about the principle than anything, for me. I was amazed at the entitlement with this one. The place she picked was one of the most expensive restaurants in town btw and I even offered to cover dinner at any other place.
