I wouldn't say we are to blame for the reason that everyone on this earth has two choices (Multiple if we had a choice in a poll) to either Yes, I'm pregnant I should be happy and will be there for my kid when he/she is born. No, I'm going to be a selfish young woman and will abuse myself using drugs , hanging out with stupid people drinking and driving (potentially putting other peoples lives at risk) and go on a downward spiral. Anyway, she had a choice before her baby was born, life was good, she was happy. Exactly what changed in that year?
In short, i think she took a risk which didn't pay off and only now she cannot handle the repercussions. I don't think it's about her fame (maybe she could have blamed this as a infant) when her parents where to blame for pushing her to stardom (when she didn't have a choice) but not now. She had her own mind whether to lead a happy and content life or the way she is living now.
Like I said, I personally think her parents are to blame as they where the people pushing her to it going through rigorous routines day in day out, think of it has a pre-cursor to an unhappy life later in life brought on by the people responsible for looking out for her.
I can't say that society is to blame, not in the slightest. people buy her records because of her raw talent. We didn't ask her to sing or push her to stardom as an infant, or ask her to take drugs and abuse her parenting rights.
As for her ex, yeah, I think he is playing it a little, afterall, he's going to get richer from this farce but always remembering that he is the one looking after the kids and living up to his responsibilities which goes a long way in my books.
Anyway, I'll stop my rambling and end with I noticed your not using an avatar uncodermom?
