What should i do?

ok well here's my story.i noe this guy and we where together before he is only 15 but usually i like older guys i mean when we were in a relationship which was only a month everything was great.i mean i didn't mind having a young boyfriend cause he did act older.but the thing is that he lives to far and his grandparents don't let him come see me.and at that time he still had feelings for his ex girlfriend he's also had a ruff child hood.he doesn't have his parents with him and he has been through a lot.even with his ex girlfriend she's always cheating on him and he's nice and they got to the same school together so it's like it was hard for him to get over since he didn't see me as much and that was only when he used to cut skool....i mean i care about him alot and think that now since we got together again a 2 months ago and then broke up again cause of the distance.he still looks for me cause some way somehow i made him happy,and i noe he wants to be with me?how can we c each other?
