So was she angry at me?

So there's this girl and, we text alot, since right now we can't see each other in person. I like her and I think she likes me. So I couldn't text her for five or, six days. And when I could finally text her back she responds all one worded and like she was irritated. So then I ask her did I do anything wrong and she says no U didn't.. Then I ask her did she want to talk about it and she says" I'd rather not".. And I ask if she wanted to TTYL and she doesn't respond. I also asked her if it was a girl thing she said nope. I didn't get it. She always eventually told me her problems but, this time she didn't. Girls what is that when you don't want to talk to the guy you tell your problems to?
