Shy girl showing interest but ignoring?

I talk to this girl on Facebook, trying to get to know her more because I genuinely like her. we're both Muslims and I think she's shown signs of interest.

- visited her high school in fall . saw her with a friend and approached her and started talking. she acted super nervous

- visited her high school with some friends. saw her with her Friends. my friend said that when she saw me she got nervous.

- I asked her on chat if we could hangout and she ignored the msg. but later when she got comfortable she suggested we hangout when I'm near her college.

- I asked for her # and she ignored the message but when she got comfortable she voluntarily gave it to me.

- when we hungout she asked me at the end if I'm ever visiting so we could hangout again.

-b4 we graduated I asked if she could sign my yearbook. She didn't put the normal signature and "have a great summer!" She wrote like 1/2 page letter saying good things about me, how I'm nice and hardworking and how as she got to know me she saw that I'm very kind. she's also very very shy.

When I show interest she backs off. After we hungout I texted her saying that she's pretty and said she looked nice when we hung out and she stopped talking to me. She still has me on fb but she ignores my txts/fb msgs. Does it seem like she likes me but is super shy?

I complimented her on her looks before. But I guess the pretty compliment kinda got her since I said it after we hungout
