“If you post a photo on Facebook, or other social media site, and tag him and it appears on his page, but none of his friends like or comment on the photo, he has blocked his world from your existence.

Or, if other women are writing on his page, yet you can't see what they write, he has strategically blocked you from this line of communication. The blocks are in place so you don't find out about the other woman or women in his life.”
