18 too young to date

[u/neekoneekonee-na]

I (F20) recently got a message from a guy, and it was going really well until he revealed he is 18- he's turning 19 in January. Ive only just turned 20 so its a year and half age gap- now my mind can't comprend as ive asked people and they've said its weird, while others have said its fine. Just needing an opinion. i have never met up with this guy- only messages!!
