Because they don’t have room in their life for people who hurt them.
Because they don’t have the patience for your bullshit.
Because it’s either block you or blow up at you.
Because they don’t want to be bothered with your drama.
Because they’re jealous of your success.
Because they have very different political opinions.
Because they don’t want to lead you on.
Because you broke their heart and started dating someone else.
Because everything you post is too much of a downer.
Because they barely talk to you anymore.
Because they’re tired of seeing the same posts again and again.
Because they hold long grudges.
