Don't get me started on this or my baby, Tara Knowles. Or any of the women on Mad Men.
While I 100% agree with this, one can't help who they love. But as we see in real life and occasionally in the well-written TV relationships, love isn't enough. There needs to be respect, communication, honesty, and more for a relationship. All qualities that Rumbelle lacks. Belle may or may not still love Rumple, because it takes awhile for feelings themselves to fade - or so I've heard.
From what I notice, a lot of the hate for her comes not only because she stopped taking Rumple's crap, but because she's friends with Hook, even though he has now sincerely apologized. I see Rumbellers whining that she's friends with the people who have abused her once, Hook, Regina, and Zelena (did I miss something? when did Zelena do anything to Belle?). And they're conveniently forgetting all the abuse Rumple put her through as well and still is even now (or maybe they didn't forget).
Like mostly everyone else, I do find Hook/Belle's friendship more genuine than Regina/Emma and even Regina/Snow. Or Regina/anyone really. They're a lot of fun together, and the actors have great chemistry.
