Ok need help

Ok so I saw this cute chick a few months before getting into the PUA. Dident have the guts to go talk to her back then. I resaw her a couple of times , just enough to have a solid memory of who she is.

Now that I actually know how to approach, never resaw her.
Turns out we have around 70 friends in common on facebook, cause fb sugest me to add her as a friend lmao.

I actually did cause i dont give a sh1t.

Was wondering the type of approaches I can do on facebook chat. I`m not an online gamer, more of a txt gamer or in person.

Advice men!
