is it wrong as a 13 year old I like someone 19 years older than me
Socially it's wrong. But. Does that stop me from wishing I had someone 31 years younger? Nope. Yet I never will have anyone. . And so I'll just die alone.
For starters, yes it is probably a bad idea. I would start by asking yourself why you don’t like people around your own age. Then ask yourself if you think that you’d start to like your peers as they age and get more mature and older.
as a 13 yr old that has dated an adult, YES. never ever pursue adults as a minor it will never turn out well they'll probably track you down or blackmail you or something trust me they are evil
