The way I see, she didn't even had time to fall for him with all that was going on. This was the first step to her mental health downfall, I guess... We can't just erase the things she did to her son, but we can't simply blame her as she was being pressured by "the best choices for her family" and society isn't kind with women in general. She went from a normal adolescent/young woman to wife to mother and contrary to what people may think, one new and perfect version of Mother doesn't take over your personality when you give birth. Her family valued hard work and talent, but society thinks a woman should stay home just take care of her children, as if she isn't a person anymore. I'm not trying to make excuses, she's a terrible mother, but just want to point out that it's no just her fault as postnatal depression is more common than you might think and nobody even thought of helping her, she was just criticised right and left. Her husband may have had the good intention to let her free, doing whatever she wanted, she was hurting and so was he, neither tried to talk about, much less find some counselling for her. And now he's blaming her too and while I know she's a bad mother, I'm pissed at him.
Wow, sorry for the long comment, I'm not even married or have children of my own. Lol
I can't see how this family can have a good ending after hurting each other so much, looking forward to see how this will work out.
