dating advice please help :( ?

Okay so i am an 18 year old girl dating a 15 year old boy. Im not a cougar or desperate or anything like that i just met this guy and found him to be one of the most sincere and genuine people I know. I thought the age difference was weird at first but Ive learned to realize the people who matter wont mind. He however, is still struggling with this concept and insists we keep the relationship at school to a minimum. I agree with his completely as im not sure how fond i am of a relationship right now, let alone one that has its drama. Grade 9 girls bother him all the time about dating someone older because they are all in love with them and he wont give them the time of day. Through older siblings or fabricated rumors, they are trying to make me look like this horrible person which isn’t helping things with the guy. As it stands right now we are sort of dating, but its a secret to most. I just need some advice because i want him to be public about it to an extent. He stopped posting things on my facebookwhen we became officially, and he’s a bit flirty with other girls. I wouldn’t mind this if he was more open about stuff with me, but im just not sure what to say since we did agree to keep things low key for awhile. He was on his facebook yesterday and just flat out didnt reply to my letter after HE had suggested we do something. Im getting a bit frustrated with things so ANY advice would be helpful. Thanks!

You do realize that this is against the law, don't you? You are technically a pedophile because you are now classified as an adult and he is still classified as a child. Do you realize that you can be arrested for statutory rape with this person? If that happens, then this is something that will stay on your record for the rest of your life, and every time you move somewhere, you would have to register as a sex offender. Your name and picture would be on a website for sex offenders. Do you also know that he does not have to be the one to report you? Any of those jealous girls can do it, and damage your criminal record for the rest of your life. I would say break up with him now...you definitely don't want him to be more public about it.
