The Girl I like just disappeared out of the blue? What is happening?

So I’m into this girl who I was mutual followers with on insta and we had been for probably 4-5 years and we used to like each others posts and view each others stories, I’ve messaged her a to say happy birthday and like to tell her hair looks good and she replied “Thank you 😊” and she seemed to really appreciate that and now lately she’s been really quick to view my stories like within the first 15 minutes and been the first viewer.

Then out of no where a couple of weeks ago, she just unfollows me but she didn’t block me I still follow her.

so I’m wondering did I leave an impression on her where she won’t forget me and will she come back at all.
