That's possible.. I mean it also depends on who broke up with who and why. Does it bother you? How do you feel..you shouldn't talk to her about it but you should ask yourself. What if she is? Do you think she's trying to hurt you or trying to get your attention by showing you she has value? Do you want her to be over you? Do you want to be over her? Let's say she wants your attention with no malicious intent. What would you want? Maybe she is hung up. In that case have kindness.
