Remember how Belle almost broke the Dark One's curse when she kissed rumple.

No one really knows if Belle's attempted kiss would have worked. Both Regina and Belle thought it would. So did Rumpelstiltskin. But since Belle never kissed him, we don't really know if a Twu Luv's kiss would have broken the curse.
