Help!?

Okay so, I'm a high school freshman, and I'm into a senior who's also into me. He's very respectful and actually friends with my older sister. I truly trust him but I don't know what people will think if we start dating. Opinions? Advice? Anything will help.

(BTW: I know, absolutely no sexual intimacy until I'm of age)

So......yeah. It didn't work out(as expected). We had been talking for a while until he hits me with a "I just don't feel what I did at the beginning". His text-yes, TEXT-essentially sounded like he was blaming me for not giving him enough attention. Well....SORRY that I was a little sidetracked and distracted because I had recently gone through some really heavy stuff. He hasn't spoken to me since December 2. And he probably won't anytime soon. I'll update again if he does finally speak to me.
