I am new on this forum, from Europe, so i am apologizing in advance for my bad grammar.

Few years ago, i had a crush in high school, but because i thought she was out of my league i never even spoke with her. Now, after few years i have a friend on college who knew her, and she told me, that girl also had a crush on me .

I added her on facebook, and she got recently single , so i have to make my move. I don't have a chance to speak with her in person, so facebook is only option... Can anybody give me advice how to make my approach?
