How to get her to like me?

[Brogan]

I met this girl a few months ago, but we barely spoke. We have each other on Facebook and we were talking for about 4 hours straight today.
We talked about anything that came into our heads and were joking about - turns out we have common interests, but neither of us said anything about our common interests. I said to her that I might dye my hair this summer and she asked if she could do it for me. I mentioned something about my family briefly and she made me promise to tell them that she said she loves them (which I fin odd) and I mentioned that I was writing something that was creative and she said she must read it. She kept saying at some stuff that she was jealous of me, strangely.
Besides talking more (both outside and online) and all that, how can I get her to like me?
Also, regarding the stuff I mentioned above - is there a chance she likes me?

I think she already does XD
