Ight. I like this girl and i need help. wtf do i do?

Just be confident and next time you see her, just go say hi:) Maybe you could bring up some memories of when you talked to each other. Tell her that you miss her. Us girls like tat kind of crap. When you approch her, don't make it akward at all. Act like you're still the friends you were! Just say "Hey, What's Shaken?" start a convrsation. Good Luck!
