My Boyfriends parents hate me! any suggestions how to get them to know the real me?

My boyfriend is younger by two years and his parents hate that hes not dating someone his age...weer still in high skool....theyve never met me and know me by only what others tell them...i have had a not so stellar past and they think im going to steer him in the wrong direction when it is the exact opposite... hes tryed to tell them that im helping him and getting him through skool but theyll hear none of it...theyre threatening to take him far away so i can never see him again....HELP! i love him and i cant live without him...
