Boyfriend advice ?!

Okayyyy so my boyfriend used to be a really bad guy (drugs, jail, etc) but he’s changed so much, and yes when I say changed I mean he’s aCTUALLY changed. My dad found out about his past & doesn’t want me seeing him anymore. We have fights on & off because it’s hard that I dont get to see him that often anymore since hes not allowed at my house & im not allowed at his (his parents know we’re having sex & they’re very religious). But recently we’ve been fighting a lot about little things but they’ve been super blown out of proportion and I’m not sure I can take it anymore. Any advice on how to solve it?
