Okay, first, if you've never spoken to the girl, you have no idea who she really is. Calm down. Clearly you think she's lovely, and that's great, but that's not the same as loving someone.
Second, if you want to find out more about her, try talking to her. Don't expect anything from her other than the same courtesy you'd expect from any other person. You need to understand that she owes you nothing but that. She's not going to suddenly fall into your arms--that only happens in the movies. Don't build this up to be a big romance before you've even had your first conversation with her.
She may even turn out to be someone you don't want to spend time with; she may value things you don't, or she may despise the things you value. You never know until you talk to her.
Start by saying, "Hi, I'm farahshaheen47." (Or whatever your real-world name is.) If she smiles and tells you her name, you can go from there.
