This movie put me in a bad mood.

I just hated it. How do you kill your son and get away with it? How do you kill your husband and let someone take the blame for it? Did he acually cheat on her ? Why in the hell didnt she take the dam medication ? Why didnt he divorce her right away? How in the hell does she have the guts to say "I want another baby, thats all i ever wanted". She got that and she killed him. I dont knowww im mad.
