The slang term for it is 'monkey branching/brancher' (in that monkeys will only let go of the tree branch they are currently holding on to once they firmly have the new branch in hand).

I don't currently know of anyone like that, but I imagine that they have issues with being alone (which we all do, technically).
As a Forever Alone person, I find it strange and foreign, but I'm sure my chronic singleness seems strange and foreign to them too.
