Negotiations between the principal actresses on the CW’s “Gilmore Girls” and the network have come to a standstill. Neither actress has agreed to a final offer, and talks have come to a halt as the series itself winds down its seventh season. Will the show return next year? That answer may not be known until after the season finale has already aired - leaving the “Girls” with no way to wrap up the show on a series finale if talks don’t go well.
