Age difference…😒

Okay so I met this guy and right off the bat he told me how old he is. He is 19 and I am 16. We really like each other and he's an amazing guy. And I know your gonna say that because I'm 16 I'm immature and don't really know but I've had a really rough life so I don't let myself fall for people.  Everyone tells me I should be 18 cause if the way I act. So now we want my dad to meet him before we start dating just so we know he likes him since my dads opinion means everything to me. But I know he will never approve because of his age. I wanted to lie about his age just until they've met and get along then I would tell him but the guy doesn't want to do that. He really doesn't know what he's getting into with my dad. I don't know what to do.
