How does she feel about me?

I like this girl. I asked her out 2-3 months ago, but she said no, but she wanted to be friends. We hanged and turned into great friends, even with her best friend (who told me 2 days ago that this girl told her that she likes me very much, but isn't that attracted to me. This friend then went on then saying that we're perfect for eachother (everybody that knew the both of us said that) and that maybe something might happen in the future).
So yesterday me and this girl hanged out the whole day. A lot of people assumed we were dating and we both just laughed it off. So when we parted ways I texted her to make sure she got home safely. And all of a sudden I got this feeling that she started acting a bit different towards me. She made sure I got home safely as well (she didn't do this even once before), we talked untill 2am which we almost never did since she'd usually need an hour or so to reply. She even said that she really wants me to come to her birthday party and was even ready to change the time of the party because I have a shitty bus connection.
Did she start liking me?
