Everyone's saying "get to know her," "get closer and wait until she's older," but that's a real reach. It's unrealistic to think you'll still know her, be close, and have a shot at her in several years' time. The cold, hard truth is that she'll probably find someone closer to her own age if you have to wait that long.
Although, being on the other side of the fence, I wouldn't have seen anything wrong with going with a 19 year old guy when I was 14 1/2. I doubt my dad would've cared too much as long as the guy was respectable (as if I'd pick a loser guy, pfffft). Of course, my dad was always pretty cool about stuff like that. I wouldn't advise going after her, though.
