LGBT: could she be into me?

I met the most breathtaking woman recently, online. I already feel a powerful connection with her that I have never felt with anyone else. Just looking at her puts me at peace. She's absolutely wonderful. We text each other each night, and she's called me a few times-- even though she isn't much of a phone person. On our last conversation she told me that I should plan a visit to see her. She offered to let me stay with her, and to show me around her hometown. This sounds like a good omen, but I am afraid to get my hopes up. Asking her directly might scare her off, and I'm afraid to do that. What do you think?
