If there's new ones with every choice or event, then you would've also been branching out towards infinity selves with every choice made in your lifetime. Not just within your own, either. Ever choice by every person in the entire world, and whatever other beings in other worlds there are, each one would call for a new universe in this theory. Many would have the same yous as other universes do, because YOU haven't changed between them, but other things have.
