I'm falling for my best friend 😩

Today he was looking extraaa cute ! I kept staring at him & ahh 😍 my eyes were eating him alive. I know he likes me & he knows I do too but I'm just not ready to make that switch from best friend to boyfriend because I've known him since 7th grade & my mom has known him for about 3 years already & id feel weird coming in one day & telling her he's my boyfriend now.. when do I know that the time is right? How did you know? Were there any specific thoughts of feelings you had about your so when yall began dating?

Btw: we're both juniors now
