So I asked my crush for lunch, she accepted, then I made the mistake to tell her I like her the day after. she told all her friends and I still have a crush on her and she said that she wants to get to know me better? She stares at me a lot, and she talks about me, I don’t know if I should give up or talk to her more. Please help.

Why would you give up !! She wants to get to know you better ! That is good news right, go for it !
