Can I get some input on this cancer girl?

I've met this cancer girl a couple of months ago online and we talked quite a bit before meeting in person. There was a period where I didn't hear from her and I took a chance on checking up on her and since then we exchanged social media, talked some more and then finally met in person. We had a great time and said we'd do it again soon. Kept talking almost everyday and it was all nice. She seemed pretty interested in getting to know me and I began to crush hard on her. I've been burned in the past so I was taking it easy and hoping to see her in person more often. Then things started to get a little cold. I didn't mind how long she'd take to answer because her tone always seemed the same: excited, all smiles. But now I haven't heard from her, out of nowhere. I thought she was busy or because it's summer and she's pretty social. I know she read my last messages because we only used our personal numbers for our meeting in person and talk mostly on messenger. I sent her a text on her birthday and she answered back but now the only interaction I have from her is her liking all my social media stuff.

I'm confused. I suppose she's not that interested in getting to know me after all. I feel it's a shame because we have lots of things in common and got along pretty well. But her silence confuses me. She's got something big coming up and I'm unsure if I should still show some support. I don't want to bother her if she's not keen anymore.

I'm a pisces and all I could figure out was that her venus is in leo, mercury in gemini and mars in taurus. Did I do anything wrong or maybe she just changed her mind? I know she got off from a relationship months ago and it's not like I'm going in for the kill. I'm fine with taking things slow and getting to know each other first and spending time together, just that the lack of communication confuses me.
