age gap?

Hello there
I’m going through an embarrassing situation right now and i think i need some advices.
So, i basically met a girl online on December 2025.
She said she was 17 going on 18, just like me.
She was born on August 2008 and i was born on March 2008.
Everything seemed to be okay.

We’re 500 miles apart from each other, i’m gonna drive to her in one week, staying with her for 4 days.
And then she sent me a message. She told me she lied about her age, she’s in fact 16, going on 17 in august when i freshly turned 18. It means it’s a 1 year and 5 months age gap.

I don’t know how to feel about it, i’m not okay about the lie, but worse, i’m not sure being okay with that age gap. it really affected the way i used to see things. not saying i don’t like her anymore. we’re not even dating yet.
I’m just asking for advices, what would you do ?

Thank you and have a nice day / night.
