If you want, you could also read up on modal realism, which is a philosophical concept that proposes that all possible worlds are as real as this one. Meaning, in short, that the you that did not go through with it exists, is real, just not accessible to you. :D

It is a very interesting read that makes you ask yourself about a lot of things we take for granted. Have fun!
