<human>: Can you condense the text into a few key points?

There is 1 girl, she is virgin 18yo. Month ago, I was in a bar where she was so I went towards her to talk, but when she saw me, she ran away to the bathroom. 

After week or so, I saw her at our house with no makeup on and she began blushing a lot and she told my friend that she now looked like skank infront of me. Few days later, she accepted my fb invite. I messaged her About week later and we sent About 20 messages together over course of 2 days and she answered enthuastically with lots od smiles, so far so good....

Few days later she appeared at our house again (my sister is her best friend) and she was very scared of being alone with me, Just like in a bar before, she was defensive I would say.

Then after few days I flew on vacation for a week and she didnt answered my fb messages when I was there. She told my sis that she is writing with 1 guy but he seems undecisive but she likes him and isnt sure About me. Then she appeared at our house and I told her that I like her but she is keeping running away from me and she answered that she has bf now, even though she is Just writing with him.

How am I supposed to understand this? I thought she was Just shy but now she is not interested? Did I Wait too long and then my bold move scared her away?
<bot>: girl seemed Just shy around me but when I told her my feelings, she told she has bf (but in reality she has not)
