So, I dated this girl for like 6 months and she ended things after we had a fight. That was like 3 yrs ago. She immediately blocked me everywhere (text, insta, facebook). Initially, I used to check if she unblocked me because I wanted to talk to her but after a few months I stopped checking and moved on when I realized I was still blocked. Recently, I just casually checked on Insta if I am still blocked and to my surprise, I am not. I don't know what made me check her profile because I never did that after I moved on. I am still single though - dated someone in between but didn't work out.

My question is - what does this mean? Should I reach out to say hello?
