Analytically speaking these are different things but it is very hard to tell since one requires a special incident to be necessarily different. Here is an example.
The Scenario: Wife and Husband in an argument
Husband: Honey, I did this FOR YOU (In this case it is used as an action), why would you think I would ever betray you.
Wife: Your not, TO YOU(In this case TO YOU is being used as a declarative because the wife is pointing out her husband's opinion that she wholeheartedly disagrees with.) everything is a game, I have reached the point where I can't take your silly games anymore.
Attempted descriptionA thing or action is "for you" when it is intended to provide you with a benefit or desirable condition.A thing or action is "to you" when it has an impact on you.
"To you" can also be used to indicate that something is being described from your viewpoint by another person, and that viewpoint is not necessarily how others see the same thing.
