Unwanted tension, how do I get rid of it?

[deepfan560]

There's this girl, we've never meter had a conversation in reality, but I saw her at a sports tournament and long story short, we are facebook friends and shared a few volleyball conversations about the tournament. Then the weekend after she went to her ball and put some photos. So I thought I'd be honest, and I told her she looked good in a private message, said that "she deserved to hear it". But it never said she saw the message, but I'm assuming she has, cos in the past days when I've gone on when she has been on, within the next minute she is offline. Last night I went on and she was to, she jumped off, so did I. Then ten minutes later I went back on again and she was on again, within the next minute she went offline again. Then twenty minutes later I went back on again and she was on but this time she stayed. I didn't approach her or say anything to her within this time, so I'm assuming it may have frightened her and I'll give her space until there isn't as much tension.
So at this point Facebook is the only way to communicate because she lives in a different city, so real life interaction isn't possible at this stage. So I just want to be friends you know, because it's not like anything else would happen, and I don't want to be a creep to her or anything. I want to get rid of the tension, but being more than just another Facebook friend.
Any advice?

She might think it's a little weird right now because she doesn't know you well... although I see no harm in your message, but girls are easily spooked... trust me. She probably thinks you want to get with her and is avoiding you. Or she just needs more time to open up? All girls are a littleshy at first. Maybe message her again and just clear the air about being more than friends?
