Hello everyone I need advice and I do not want any judgment so any negative comments keep to yourself, thanks.

I really like this guy but I don’t know if he likes me back. I’m 21 and he’s 45. Age is just a number in my opinion when you’re an adult. Because of the age difference I’m not sure if he likes me back and also if he does how dating exactly works and such with a 24 year age gap. My dad asked for his number tonight and he said yes then looked and smiled at me and I thought okay I’ll have my dad give me his number and I’ll text him Saturday or Sunday so it’s not right away but idk if that’s weird. My dad gave me his blessing to date the guy which I wanted bc they’re friends and also super close in age😂 I’m overthinking this I know but it’s because I do really like him and I want to date him so really any positive advice would be great so thank you😊
