I will add the screenshots here, so it makes sense.
Basically I hung out with this girl for a while, and realized she ́s my type after a while and asked her out, rejected me month and a half ago. Not in a direct way, but indirect, I never got a straight no in person. I tried flirting after that, and moving it forward, she would play dumb or ignore or dismiss it. I started ignoring her and after 3 weeks, she reached out asking why am I ignoring her?
I told " am not. Why would it bother you?"
To which she responded "Because I didn ́t do anything for you to do so..." etc. Here we reconnected here just for 2-3 exchanges.
Next day, I see that I am added to the close category of friends in her insta story for some reason, I see the green outline around her profile. I watch her story and don ́t react.
Next day, I am sharing this story from this other girl, who is my partner and who posted how we won a championship in dancing competition (it ́s my hobby and what I do). And then she reaches out saying congrats...

The thing is, I am out my town now and will be for couple of weeks and she seems to want to reconnect, but don ́t know how to play the long game, I was never good at it...Like I want to keep it low investment, nothing too persuasive, not saying anything that fits her agenda etc. Just keeping it alive. So I should post stories definitely, but what about text game?
What ́s the best way to proceed and answer? Thank you
