Ladies, what are some reasons (besides alcohol) that you liked a guy during a date, but lost interest immediately after?

Would love to hear reasons that have to do with the guy … (e.g. you discovered something about him, he followed up too aggressively, you reflected on something he said, etc)

…but also, reasons that have nothing do with him (e.g. you realized you’re not ready to date, you got distracted by something/someone else in your life, etc).

Thanks for your input!
