I'm sorry people are saying the husband is sweet? It seems like she has not a single person she can emotionally rely on this household. He laughed at her, and completely shut her down, making her feel helpless. Not to mention her son hates her, and the maid clearly looks down on her.
Saying that he's still only 15 years old, when she most likely got pregnant at 16 when she thought she had no choice BUT to marry... I hope that it is the characters saying it and not the author.
The mother... she doesn't stop her daughter from being selfish, and then later says she's a failure in front of both her, her father, and the brother she despises, despite being the reason she is like that. I don't think that's ok.
