Girls, why did my ex unblock me?

Anonymous
Girls I need advice, so my ex (20f) broke up with me about 2 months ago because I (24m) was insecure and jealous and over thought about having a future with her. We met at work and We dated for just about a year and we were happy together but it didn't work out by our 1 year anniversary. I was crushed and tried to fix things for weeks until I started the no contact thing for a a month.

The reason for this message is because while trying to fix things, she blocked me from everything social media, which I was gonna do to get her off my mind for NC.

Fast foward to 2 days ago she decided to unblock me from facebook... what does this mean?
