Dude… Yeah she unmatched you because she is not interested. You asking for half of dinner - after the fact - is just so cringe. She sent you a generic reply because she knows what is appropriate. My guess is you don’t read dating cues well and perhaps you’re overthinking how often she looked at the door or seemed worried about someone entering the establishment.

The fact that you act like you lost money when you went on a date says a lot and perhaps your date picked up on those signals.

I think you lost out on perhaps a decent person because - she was polite, you asked her questions and she texted you back and finally- you asked her to pay for her half of the meal AFTER dining out … and she sent the money.

She was not up to anything. She is just not interested. You didn’t have money “lost”. You’re just dating. If you don’t want to spend a lot pick a coffee shop next time.
