what I'm saying is everybody played a part in the mix up.

You did nothing wrong. You raised and honestly thought everyone folded. Collected the pot and released your cards.
Protecting your opponents action is not your responsibility. (although you would have if you had seen his cards.)

Honest mistake by the dealer or he wouldn't have pushed you the pot.

If SBs cards were in view you and/or the dealer would have stopped the action for him
If SB was paying attention to the game he could have stopped the action.
