What kind of relationship do u think was between pink, yellow, and blue diamond?

I thought there was a love driehoek between them. roze and blue diamond were together and yellow was jealous and shattered roze so she can be with blue is why she was trying to get her to forget about pink. but after seeing " Jungle Moon" after the way roze might have acted portrayed door Stevonnie, I think a maybe they could've had a mother-daughter relationship. what do u think?
