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

I thought there was a cinta segi tiga, segitiga between them. berwarna merah muda, merah muda and blue diamond were together and yellow was jealous and shattered berwarna merah muda, merah muda 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 berwarna merah muda, merah muda might have acted portrayed oleh Stevonnie, I think a maybe they could've had a mother-daughter relationship. what do anda think?
