Perhaps true love is willing to give up the thing you want most for the person you love.
For example, Belle had dreamed of adventure and willingly gave that up to be with Rumple after he had let her go the first time. Rumple desired to find Bae, but maybe in that brief moment when he kissed Belle, he was willing to give up the search for his son. When he thought Belle was tricking him, Rumple was able to undo true love’s kiss because he wasn’t willing to give up searching for Bae for something that wasn’t “real”.
Milah and Cora weren’t true love because they were unwilling to give up what they wanted most for Rumple. Milah ran off with Hook because she wanted adventure and Cora ripped out her own heart because she wanted power.
At the beginning of the season, weren’t Mulan and Aurora talking about how “Love is sacrifice”?
All magic comes with a price!
