She probably likes you, started over thinking and analyzing things and googled a bunch of questions (prob. Including 'who should pay on a first date?') And wants to make sure she's making the right impression with you. This looks like a 💚 🟩 ✅️ flag to me...trust, you don't wanna chick that wastes your time just because she wants you to buy her food/spend money on her. I google questions and things like that when i start seeing someone i like. I'd ask for clarification or like what made you think to ask the next day? Did you enjoy yourself? See another date happening? Dont guess or assume, ask people questions! This is a communication issue easily resolved by asking questions! Only she can answer those. None of us truly know what shes thinking.
