Please Help ? Boyfriend problems ?

Hello, I am a 13 year old girl with a boyfriend who is one year older. He isn't such a "goodie 2 shoes". He's more like a bad boy. Drugs, bad grades, etc etc. But he's really sweet & I know the only reason he is hardcore, is because of his past. School is almost coming to an end, & he will be going to high school. How can we keep seeing each other over summer if I live 2 miles away from the school I go to ? (That was the only option since the other schools had a bad rep.) My mom doesn't let me go out with guys, unless they come over. But my mom wouldn't approve of him. Any ideas ?
