Is OTHER wrong in the post ? POST : English isn't my first language.

I'm a regular at my local bar and spend a lot of time drinking with familiar faces and watching the game there with friends. The other day a woman approached me there and started making small talk and we got to chatting fairly well. She was clearly flirting and I was interested at first, but she said "you can buy me a drink if you want" and I started laughing because it seemed so presumptuous. She must have thought I was playing around because we went back to talking and she invited me out for dinner the next night and I agreed.

We went to dinner and talked more and everything was going well until it came time to pay. The bills came and she didn't even reach for her wallet once, just looked at me expecting something. I told the server two bills and paid for my own and she just kind of stared at me then paid for her own. When we went our own ways I texted her and told her I didn't want a second date.

It put me off that her initial idea of flirting is by suggesting I buy her something, it didn't come across as if she seen us as equals, almost like I was expected to impress her even though it was her who approached me. Then when we went to dinner even though she invited me she expected me to pay automatically instead of splitting. She is otherwise very polite but it came across as very entitled like I had to pay for the privilege of her time or I'm expected to put her on a pedestal. It made me feel like she thought she was better than me. My friends say I am being an asshole, and so did she when I told her no second date. AITA?
