I am a 30 yo woman dating someone 13 years older. Literally nobody cares. Unless you're dating a literal teenager or there's a weird dynamic going on, it's highly unlikely that people will give you shit for it.

"but someone on twitter said something". Twitter is filled with children, trolls and shut-ins with very little life experience. Same with Tiktok, many commenters are literal kids. It's probably for the best if kids think age gap relationship are creepy if it prevents grooming. If you're so insecure about your relationship then maybe don't be in an AGR.
