Milah is disliked by most people because the first time we see her, she is being mean to peasant Rumple, and everybody loves Rumple, so immediately the audience is being set up to dislike Milah.
I don’t hate her for being mean to Rumpel.. she doesn’t HAVE to stay in love with someone I hated her because she didn’t CARE about her child. and because I think she instigated Hook to be bully because SHE was such a bully herself.

and Once_dude, she didn’t have to ask why he left the Ogre wars, he TOLD her. because she was pregnant. “all for the boy” he said
