Hey first please dont judge me, i legit need some advices

i basically look almost 10 years younger than my real age.

I'm 33 yo and told my GF i'm 25 yo, It's been a year now since we are dating, and she is 21 yo.

I used to go out a lot at night and tell every girls i met that i'm 24/25, all of them believed me, so i ended up having this bad habit to lie about my age in club/bars/party settings

I even had girls telling i look youger than my fake age

The night i met her was at a bar, she was super interested, i lied about my age this night as always :/, anyway she text me the day after so we can hangout again, i accept ... and here we are now, 1 year after, still dating, met her parents & familly multiple times, everyones like me

We never had a single argument, she is a nice girl with no red flags, and everything is going fine

I'm not sure what to do now, either tell her everything and see where it goes, and just dump her depsite she is a nice girl ? I feel stuck atm
