Grammarians have for years condemned as ungrammatical the English phrase between you and I, insisting that the correct phrasing is between you and me,  with the objective case after a preposition. Such condemnations, however, are obviously unfounded, because Shakespeare himself, in The Merchant of Venice, wrote, All debts are cleared between you and I. 
The phrase between you and I appears infrequently in Shakespeare's writings most seriously weakens the argument above.
