Age & height difference, need advice and support!

Okay so I'm a senior this year (in highschool) And I normally really hate dating people that are younger and/or shorter. It's nothing against them, it's just a preference and I feel awkward being the bigger person as a girl. But there's this guy I've been talking to lately but the thing is, he's a freshman. And he's shorter than me.. I'm like 5'5''-5'6'' but he's only like 5'4''. He's super adorable, cute, and sweet. And honestly when he gets a little taller and older he's going to be hot asf, not that he isn't already attractive though because he is. I'm just having a hard time with the age and height difference. But every time i see him, I feel my heart jump and my stomach drop.
