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

I thought there was a l’amour triangle between them. rose and blue diamond were together and yellow was jealous and shattered rose 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 rose might have acted portrayed par Stevonnie, I think a maybe they could've had a mother-daughter relationship. what do toi think?
