Is it wrong to keep asking until I get a “No”?

So I finally went on a first date with a girl I’ve been wanting to get to know better; and it was amazing. We talked for a few hours and went to two different venues. At the end of the night we hugged and she told me to let her know if I wanted to go out again. To make a long story short: I’ve been stuck on the fence on whether she is actually into me or not. There was a bunch of minor occurences prior to the date that indicated she was, but with one major thing thing that puts doubt in my mind. We will message for a short amount of time, and it will typically end abruptly with me being left on read. She rarely ever texts first, and I almost always initiate a message. This causes me to overthink and stress about the situation. Could she really be into me and not show it through messages? I know the common theme is that someone that is interested will show interest in that aspect, but I’m still holding out that this may be an exception. My current strategy is to keep asking her out (reasonably), and if I get a rejection then I will stop. Is that ok to do?
