Is it wrong to date a 20 y/o at 16?

Before anything I must say I knew him before he turned 20 it would be creepy if I didn’t. I met him 2 years ago when he was 18 and I was 14 I shortly turned 15 a month or so later. We have been close friends because he had a girlfriend at the time. They broke up and we started talking more and we had feelings for each other.

This year he turned 20 a few days ago I turn 16 in 2 months. I forgot his age I didn’t really think about it until it just came to me that he just turned 20. He met my mom and everything he’s very respectful and all that good stuff. I would like to add I’m young and don’t know everything so I’m asking for advice and help.

( Don’t think because I’m younger than him he’s taking advantage of me we just kiss sometimes and I’m a little feisty so I stand up for myself and always confront problems. I try to stop little problems before they get bigger)

Also I would like to add I was never pressured by him under any circumstances
A 4 year age gap is legal in my state
I would never be with someone who is 20 and I’m just meeting them😂 the only reason he’s an option is bc I knew him before he was 20
He was 18 I was around 15
