Here's my take on it all... and this is just an opinion.
Mary is a little batshit. We all know that. She also cares deeply for her kids and she's "grown up" and made them her life's priority. Scott has not. Scott has always been a selfish junkie that has been completely incapable of maintaining any relationship, ever. His 2 marriages, his kids, STP, VR, Doug Grean. You name it. Every relationship he's had has deteriorated due to his demons.
Now I do think Mary is setting up another book. There are so many questions after her statement. Is she not bi-polar? How is this possible when her whole book was about dealing with the condition? Her comments about dating a "normal girl" feel like a subtle pot shot at Jamie. She hints that there is so much more she wanted to share but didn't to protect her kids. I mean, it's the perfect set up for more questions and drama.
And you know what, I'm not sure I can blame her. She has to provide for 2 kids. She's clearly bitter and angry that society is set up to enable a sick man to continue his death spiral. And if society is set up to capitalize on the illness of her father's children - to "chew him up and spit him out" - then it seems totally fair game for her to capitalize on that same society by releasing a book as a means to an end to providing for her kids. It would be one thing if she was always out in the public, always bashing Scott, and trying to be a celebrity. She's never done that. This would be for cash to provide for her kids. I'm not going to judge that too hard.
As far as Scott's side... I'm sure he has a reasonable gripe too. From his perspective I'm sure he felt like he was there for Mary when she had issues. And trust me, SHE HAD A LOT. She admits as much. And he felt abandoned when she wasn't there for him. Mary would tell you once you have kids it's time to grow up. Fair. Scott would tell you a disease doesn't pick and choose when to strike and the right thing to do is stand by your man and be there for the person that was there for you. Also fair. And yeah, I'm sure Scott didn't love visitations with some 3rd party observing how he interacts with his kids. I'm sure Scott's unstable nature forced Mary to distance herself and her kids from him. I'm sure Scott was crushed by that.
It's a two way street and there's no "right" and "wrong". I think Scott was surrounded by forces he was too weak to stand up to, unfortunately. The was a broken man in a lot of ways and as the Deleo's said that lifestyle fed into his unique genius to a degree. But it didn't have to.
The whole thing is sad. I feel like shit for supporting Scott's habits. I feel like shit for his kids. I'm not going to judge anyone here, including Mary. I'm not naive enough to say that her motivations are financial to some degree, but hey, we have to make money to live.
As far as "bashing Scott after he died" - I think her point is he died a long time ago. At least to them. If you look at his demeanor. His eyes. His performance. His personality... there's a lot of truth to what she's saying. He was a zombie going through the motions at the end. We all know it. And it's hard to get right and healthy when the world feeds on you behaving this way.
At least we have his music. It is a beautiful part of what he gave this earth. A unique and world class gift. Was it worth the baggage that came along with it? No. And I don't blame him for being sad or his kids/ex wife for being bitter and angry. But there's a lot of sadness now - not just them or Jamie but his bandmates, us the fans etc etc... So I'm sorry for y'alls loss too. Scott meant a lot to all of us here.
