Maybe X&Y will introduce some sort of a way to de-evolve Pokemon..? We can only wonder.
EDIT: wait, then it would turn the entire Pokemon franchise into a Digimon copycat. NVM

Answer 2

They cannot devolve once they are evolved as the actual trigger is when they level. Over here!

Answer 3

One way to PREVENT evolution is to press B while its evolving or give it the ever stone. You could also lay an egg of that Pokemon by breeding it with a Ditto. Before you judge your Pokemon first try to get along with your Pokemon. First let me know what Pokemon you're using. I know many ways to get along with any Pokemon depending on the kind.
