Girl doesn't respond to messages/texts for days, is this normal?

Anonymous
First, I met this girl and we hit it off pretty well. A lot of the same interests, similar personality, similar goals, share same sense of humor, etc.; overall, we have a lot of chemistry together. So, we've been messaging back and forth, but her replies are always so short and they don't really progress the conversation. I am usually the one always asking questions to progress them. Anyway, her messages are pretty sporadic and can take days for her to respond. I didn't ask about it, but she let me know that the reason to why her messages can take so long is that she has A LOT of anxiety and is a pretty quiet/introverted person (she wanted to make sure to let me know it's not because she doesn't like talking to me). When she does respond, I usually respond within a few hours.

There is only so much waiting around I can take. Would it be a good idea to just not respond to her next reply for a few days (in order to give the impression that her untimely responses will elicit the same from me)? I really do genuinely like this girl and would love to go out with her again. I'm usually a pretty patient person. However, there is only so much patience one can take,

Other details:

1. I've called her for another date a couple times. First time, she didn't answer, but responded the next day apologizing for it. Second time, I haven't even gotten a response back yet (I called a couple days ago).

2. Like I said in a previous sentence, she is pretty introverted and has a lot of anxiety (and I feel like this is why I get sporadic replies, but then part of me thinks that if she was really interested in my, she would make a better effort to respond back...)

Any advice you all could give would be greatly appreciated. Thanks!
