I took this to mean that Rose was like a mother figure to Amethyst and Greg was her best friend. When the two fell in love, Amethyst lost both of them, explaining why she is so uncomfortable whenever Rose is mentioned. It is also quite possible she does, in fact, hold Greg responsible for the fate of Rose, given that if they had never met, Rose would still be around to support and care for her.
