I like this girl

So I like this girl and me and her both have feelings for each other and she’s a freshman and i’m a sophomore but here is the thing i’m 16 right now and she is 15 but i turn 17 in June and she won’t turn 16 until December and idk i just need to know if that is like a weird age gap i’m sure i’m over thinking it but idk i just need other peoples opinions
