Mary Forsberg Weiland, Scott Weiland's ex-wife and the mother of his two children, has strong feelings about the former Stone Temple Pilots' frontman's death.

Mary wrote an open letter published in Rolling Stone, in which she describes the complex relationship Scott had with their kids, Noah, 15, and Lucy, 13. Mary, who married Scott in 2000 but split in 2007, says their kids actually lost the former singer "years ago" due to his "multiple illnesses."

"You might ask, 'How were we to know? We read that he loved spending time with his children and that he'd been drug-free for years!' In reality, what you didn't want to acknowledge was a paranoid man who couldn't remember his own lyrics and who was only photographed with his children a handful of times in 15 years of fatherhood," Mary writes. "When writing a book years ago, it pained me to sometimes gloss over so much grief and struggle, but I did what I thought was best for Noah and Lucy. I knew they would one day see and feel everything that I'd been trying to shield them from, and that they'd eventually be brave enough to say, 'That mess was our father. We loved him, but a deep-rooted mix of love and disappointment made up the majority of our relationship with him.'"

Mary claims her children were "replaced" when Scott remarried. In 2013, the musician married photographer Jamie Wachtel.

"They were not invited to his wedding; child support checks often never arrived," she claims. "Our once sweet Catholic boy refused to watch the kids participate in Christmas Eve plays because he was now an atheist. They have never set foot into his house, and they can't remember the last time they saw him on a Father's Day."

Still, despite their troubled relationship, she does praise Scott’s incredible talent.

"So many people have been gracious enough to praise his gift. The music is here to stay," Mary writes. "But at some point, someone needs to step up and point out that yes, this will happen again -- because as a society we almost encourage it. We read awful show reviews, watch videos of artists falling down, unable to recall their lyrics streaming on a teleprompter just a few feet away. And then we click 'add to cart' because what actually belongs in a hospital is now considered art."

Mary makes it clear that she doesn't want fans to glorify Scott's death.

"I won't say he can rest now, or that he's in a better place," she laments. "He belongs with his children barbecuing in the backyard and waiting for a Notre Dame game to come on. We are angry and sad about this loss, but we are most devastated that he chose to give up."

"Let's choose to make this the first time we don't glorify this tragedy with talk of rock and roll and the demons that, by the way, don't have to come with it," she adds. "Skip the depressing T-shirt with 1967-2015 on it -- use the money to take a kid to a ballgame or out for ice cream."
