I've known this girl for a couple of months n always thought she was cute. I met her through some friends and she doesn't hang out with them anymore. I saw her for the first time in 2 months last night and she said she missed me. I was called up to the stage so I had to leave and couldn't get her number. I'm not the best when it comes to attracting women. So what's the best way to get her number and start talking more? I know she has a Facebook but ppl have told me I should wait 3 days to add her then another 3 to message her and ask for the number. Is that true?
