How many friend requests did you send out for these other platforms? (Exact number.)
How often do you offer to create or join a multiplayer game? (Rough estimate.)

Maybe you're just the kind of person that appears disinterested in becoming someone's friend, so you need to make the first step, because if you don't nobody will know that you want to be their friend. 
And maybe your friends are the same kind of people and you are basically playing a chicken game where you all want to be friends with each other, but everyone feels like you can't simply be the first one to express that and it needs to "happen onto you" (a dumb belief), as would be expected of 4chan spaghettilords.
