Opinions?

So me and this girl have been texting for almost a week. It was all good we were texting a lot flirting, and initiating closeness trying to get to know each other. So we go on a date and everything is good. We ended the date with a hug and a kiss (she leaned in first). After the date the text start slowing down and the next day getting less. Then today she messaged me saying “I did some thinking and I don’t see this going further romantically, I wish the best for you though :)”. Am I looking at this wrong as if something I did or maybe she just wasn’t ready for anything “real”?
