I have this girl on facebook who is a 10. I added her 2 years ago and we talked but it never went anywhere. I even had her number once but it did not lead to seeing her in person. She is now posting half naked pictures and its extremely hot. I mean HOT! I messaged her saying HEY like 6 months ago, and this morning but once again no luck.

How should i approach this girl (on facebook). I have a similar friend who i haven't messaged ever and is almost as hot. But this is the girl I want.

Please reply with your advice, thank you.
