Ex girlfriend acts weird on social media?

Anonymous
My Ex girlfriend and I broke up 18 months ago... about 6 months ago I receive an apology from her following a recent breakup of hers which made her realise how she appreciated me. About 2 weeks later I receive a follow request from her on Instagram in which I accepted but didn’t follow back (I wasn’t been taken as a rebound). She later unfollowed when I didn’t reciprocate this. A couple of weeks ago, my friends inform me that she has been adding them on social media... keeping in mind she didn’t know these friends of mine that well when we were together. Last week, she followed me on Instagram again...
