Can I be real?
It's entirely possible that she thinks about you zero percent of the time. It's entirely possible that she stumbled upon something on FB and decided to just block you because she didn't want to deal with it.
I know this sounds horrible but once I go zero contact I don't look back. I can't even begin to tell you how many people contact me months and months later and it's a complete surprise to me because they tell me they never stopped thinking about me. Me, on the other hand, out of sight, out of mind. I'm too busy keeping my head above water with this thing called basic functioning to be thinking about people I pushed away and don't want in my life anymore. And I think "gee, maybe you should get a hobby instead of pining for me!" But of course I don't say that as it would be rude. Once I push someone away, I don't want them back, even if they think I'm the greatest thing since sliced bread. Maybe I should stop treating people like they're actually something special so I can just be left alone.
