… butterfly wings? their relationship is like a romeo and juliet type relationship

i saw this movie 7-8 years ago (i am a 9th grader but saw it 2nd grade) the movie is english, saw it on netflix, has colors. there was a scene where the green guy wanted to rescue the butterfly woman but a friend of hers said he wanted to and they had an argument. the butterfly woman is a princess and she has butterfly wings and falls in love with the green guy who is bald.
