Relationship advice?? Helpppp

Backstory: I’m 17 turning 18 in February. I am in lovee with this guy, I’ve been in love with him for 3 years now, he loves me back and all. I’ve tried to speak to my parents 2 already, they didn’t agree.. they always say education first. We have been in a relationship for 1 year now, his family knows about us but my family doesn’t. We both know our moms don’t talk and don’t like to be in each other’s presence but it’s not their life. We both really want to be in this relationship. I plan on telling my family but they are super super strict when it comes to dating. I’m indian so they believe education and career before anything. I agree in that, if at some point in this relationship I feel like he is in the way of my career. I will stop this relationship myself but for now all he does is support me, my parents started dating when they were 18 as well, they got married at 20. How is it fair they got to date at 18 and I cannot!

Any advice how I can tell my family about him and they accept him. They are super strict. Please any advice on how they can accept him.
