Regardless of your online and telephone history, you only saw this girl in person for a couple of days, and were really only alone for one. IMO it is unreasonable to expect anything to happen, and it doesn’t mean the girl is any less into you. She sounds really shy and will need time, especially in light of her recent breakup.
I would feel her out about a second visit, which would involve a lot time where it’s just the two of you.
OTOH, starting off with a long distance relationship has never made much sense to me. Have you tried OKCupid and other dating sites where you can find local people?
