I have to agree with justme659, most likely shes just scared and nervous about meeting with u and probably asking herself the same questions ur asking like, have u been seeing other people this whole time? is she setting herself up for heartbreak? I have no doubt that the thought that u may kill her and chop her into little bits is floating around in the back of her mind too, thats enough to scare anybody into running away. But the fact remains this is someone ur involved with long distance or not and if u cant ask her if shes nervous or if shes been seeing other people or if shes afraid that you'll hurt her something is wrong.
