What did my Ex Unblock Me & ReFollow Me on all Social Media's?

Me & My Ex broke up Last Month and within 2 days after the breakup She Unblocked Me on Instagram & Twitter and every now&then she'll like one of my post of Instagram or favorite/retweet one of my tweets on Twitter. Also She'll subtweet a slug towards me every so often that I know is obviously about me but when I confront her about the subtweet she'll say "It's Not About Me"... So What does this mean cause I'm very clueless when it comes to females?
