My ex followed me again on Instagram. Does it mean anything?

So the girl I was dating broke up with me first a couple of weeks ago but took me back, but then I broke up with her a week ago, but I never imagined us not keeping in touch.

When I broke up with her she instantly deleted me on snapchat, Twitter, and Instagram but I still followed her. It's been a week and she just now followed me again on insta but still has made no effort to contact me.

I still wanna talk to her. Does this mean anything or should I wait for her to say something?
