Did I do something wrong?

Hi guys , So I replied to this girl’s story that I kinda had my eye on (Im 23 and she is 23). It was a story on which she was smoking weed - so I decided to say “ Yo we should smoke sometime”. She then replies within 10 mins “Yo that sounds cool ^^” , liking my message even. Then I ask her 10 mins later “ you know some smoke spots around town?” and she hasn’t replied or read the text - its been 3 days and she keeps uploading stories on IG. So my question is : Can something be done or should I just unfollow her?
