AITA for feeling put off when a guy I’m seeing paid only for his own concert ticket? (23F, 23M)

I (23F) have been talking to a guy (23M) for about 2 weeks. He seemed really interested from the start — he said he had been noticing me for a while, and when we finally started talking, we clicked quickly. We would talk for hours and there was definitely some chemistry.

Recently, he invited me to a concert and asked if I was free on a specific day. I said yes, and we agreed to go together. A few days later, he suggested we should buy tickets so we don’t forget.

We picked the seats together on my phone, and then he said he would transfer the money. Then I see that he transferred only for HIS ticket.

This is where I started feeling off. It’s not that I expected anything specific, but something about the situation made me feel less excited. Not that I’m homeless or anything, but I feel like the should’ve paid for the whole thing. It changed my perception a bit, and since then I feel like my interest has dropped.

I even considered canceling and saying I couldn’t go, but I didn’t go through with it. Now I’m just confused about whether I’m overreacting or if this feeling is valid.

AITA for feeling this way and reconsidering whether I even want to go?
