How long should you get to know someone on a dating app before going on a date with them?

My mom says she is scared of me because I met this guy on a dating app that I like but have only known for a week. He says he wants to meet me in person and take me out on a date. She tells me that you should be talking to this person for at least a year before planning to meet them and find out everything you can about this person and still have someone with you on the first meeting for safety reasons. I told her it's a bit unreasonable for her to be like that but part of me says that she makes sense. What's your opinion for someone trying to find someone to settle down with?

My parents are scary. I'm 22 and living at home due to financial reasons. They think that I'm naive and irresponsible and that I'll go fuck around if they don't control me which is not true since I have made it clear to the guy I'm dating that I want to wait till marriage. I tried telling her that first dates are what sets the tone of the relationship but she thinks that a week is too early and if they disapprove I can't leave the house. How do I convince my mother I'm doing the right thing?
