He’s been pursuing me, then sent me a spreadsheet asking to be reimbursed for our dates?? Am I overreacting?

Hi everyone, I (F23) have been dating this guy (M32) for a little over a month now. He was very persistent in pursuing me, constantly texting, making plans, asking me to go on runs, bike rides, and beach days (we live in Florida), and inviting me to dinner, bars, and even paying for Ubers to and from his place. We were hanging out at least 4 times a week.

Everything felt like it was going somewhere. He’d been slowly building things up and even waited weeks to finally kiss me. Then, out of nowhere, he sends me a literal Excel spreadsheet with a breakdown of dates, how much he spent, and a column with my name, asking me to reimburse him. I’m attaching it because I truly can’t believe it. It felt transactional and weirdly formal, especially since he was the one initiating nearly all the plans.

What’s even more confusing: after sending this, he still insists on seeing me and continuing to date. Like, you want to invoice me and kiss me?

And for context, I’ve picked up the tab quite a few times ,dinner, drinks, etc. , without making a thing of it. I’ve never asked him to pay me back or keep score. I thought we were just getting to know each other and splitting things organically like adults especially since he’s about 10 years older than I am.

So am I overreacting or under-reacting, I can’t tell if this is just him being “organized” or if it’s a huge red flag.
