What does your instinct tell you? I've never met her personally so it's little difficult to read her brain. There are two things - Sometimes it may seem tide is going in your favour but the outcome is often counterintuitive. One of my crushes said that she wanted to come to me(@3am) & that I should buy this or that gift! I thought maybe she liked me because there's no angle that makes it clear she wasn't interested in me. After a month she says - She has a BF and it was true. I wasn't aware of it as she never bought him in our chats (that can span a kindergarten textbook)! At other times it may seem that tide is against you. Basically, the girl tries to outsmart you by pretending that she's not into you... In fact, she can be a lot into you. They're just testing.

In nutshell, girls are really weird creatures. So I usually keep things upfront while talking to them. Whether she likes you or not is not less than an outcome of a coin flip biased by her decision. You should ask her out sometimes around for lunch or dinner and see how it goes. ATB.
