forbidden to talk to the loml😭

So there’s this guy. he’s the absolute best. he healed my broken heart and has turned my life around for the better....but there’s one problem. my parents have forbidden me from seeing him bc he has a past. his past is the past. he’s a total different person than he was in highschool. i’m still seeing him. i’m just doing it without them knowing. i love him so much ughhh how do i eventually tell them? fr stressing bout this !!
