I’m really confused

So this girl was liking my ig story’s for a while making comments on my post. Eventually she dms me about something that I posted on my story I’m like whatever you seem like fun what do you like to do. Eventually I ask for her number and she gives me it. Sounds like it’s going into a good direction and that was on Saturday and then eventually Sunday we’re texting but then she leaves me on read when I said oh I got to teach you how to play pokemon go some time. But then 3 days later she’s going back to liking my ig story and it’s literally a pic of my car what should I do reengage with a totally new topic something like hey what’s up haven’t talked to you in a bit. Something light ofc.
