I’ve been dating this guy for 8 months and I’ve hid him from my parents. HELP

Okay so we met in November last year. I was 17 and he was 18. Since then we have turned 18 and 19 respectfully. We live in the same area but we don’t hang out because we can’t get together due to my parents not knowing. I started working at the same place he works about 3 months ago. Now that we get to see eachother like 2 times a month only at work, I’m starting to really crave more time hanging out with him. Outside of work hours.

The issue is I have been hiding it from my parents for the entire time. I don’t know how they will react since previously they haven’t responded well when I mention the idea of dating. I don’t know why specifically, or what the reason for their strictness is. I really think it’s time I tell them because it’s eating me alive.

I know I’m 18 and legally allowed to make my own choices, but I also live under their roof and I don’t have a car. I am going to get a car within the next month or two, so that will add another freedom and way I can see him. And I think once I have a car it will show more maturity and HOPEFULLY gain their trust more.

I don’t know what to do. Should I wait to tell them until I have a car? How should I even tell them? I don’t think I’ll be able to say it in person, so I have a text written out. I think sending a text to my mom directly would be the best bet, and giving her time to respond to me.

Any advice is really helpful guys. Please.
