Demi Moore’s raw ‘Inside Out’ reveals rape, why marriage to Ashton Kutcher crumbled

She's giving us Moore.

Demi Moore pulls back the curtain – or perhaps more fitting for the 56-year-old Hollywood veteran, the sheet that is her signature, shiny black hair – and details her triumphs as a mom, as well as her substance abuse battles and her three divorces in her memoir “Inside Out” (available now).

Last week, she told People magazine that her book was shaped by a concise yet complicated inquiry.

“I centered (it) on a fundamental question, which is, ‘How did I get here?'” she said. “Coming from where I’ve come from, how did I get here?”

It’s the question she asks from the jump – in the prologue, a gripping account of the moments leading up to her 2012 hospitalization, which, by her account, included “a hit of nitrous oxide” and “a puff of synthetic pot”.

Yes, the “Striptease” actress seemingly bares it all. Here are some of the candid revelations.

Demi Moore details rape at age 15

Moore's parents were far from the ideal. Her mom, Virginia King, was a teen when Moore was conceived, and the man she knew as her dad, Danny Guynes, who was less than a year older, had a tumultuous on-and-off relationship. (Moore's biological father is Charlie Harmon.) She and her younger brother, Morgan, were uprooted often, even kidnapped by her "dad" Guynes once.

When Moore and her mom were living on their own in an apartment, a man befriended them, who made Moore "slightly uneasy." One day, when Moore entered the apartment, the man, who she says was "three times" her age at the time (15), was present.

Moore writes that the man raped her, explaining, "For decades, I didn't even think of it as rape," but rather "something I caused, something I felt obligated to do because this man expected it from me." The man later insinuated Moore's mother was privy to what had occurred.

"How does it feel to be whored by your mother for five hundred dollars?" the man asked her. While Moore is not convinced her mother knew what would transpire that day, she doesn't condone her mother handing over the key to their apartment where the two would be unsupervised.

"That's not what a mother does," Moore writes.

Her struggles with substance abuse

Moore writes of her relationship with alcohol: "The problem was, when I did have a drink, I couldn't stop; there was no little voice in my head saying, That's enough, Demi. There were no brakes."

She also reveals that while living in Brazil to film "Blame It on Rio" (1984), she began doing "a lot of cocaine," so much so she "nearly burned a hole through my nostrils." At the peak of her cocaine usage, Moore says she went through "an eighth of an ounce every two days by myself."

At the request of "St. Elmo's Fire" director/co-writer Joel Schumacher and producers of the 1985 feature, Moore went to rehab and got sober.

Meeting Ashton Kutcher and feeling 'electricity'

In spring 2003, Moore met her eventual third husband in a New York hotel room where friends gathered before having dinner, where, Moore writes: "it was like nobody else was there."

They "stayed up the entire night, still talking, telling each other our life stories – and understanding everything the other person was saying," Moore remembered. She described "an ease between us, a deep comfort – and a lot of electricity." She insisted the two "couldn't feel" the 15-year age gap.

"When I met Ashton, it almost felt like a do-over, like I could just go back in time and experience what it was like to be young with him." Still, the difference in age made for at least one memorable story. Moore said when she informed second husband Bruce Willis that she was traveling with Kutcher, he responded: "You are such a good mom," assuming the "That '70s Show" star's presence was for their three daughters' enjoyment.

On Tuesday's "Good Morning America," Moore reflected on the relationship with Kutcher while speaking with Diane Sawyer.

“I think that I had been responsible for so much of my life, and all of a sudden, this window opened up where I was safe, I had money," she said. "(Kutcher) loved my children. It wasn’t something he feared."

Losing herself in threesomes, alcohol

Despite a strong start, Moore found herself compromising for her young love – throwing away years of sobriety and inviting others into her marriage.

When Kutcher said he didn't know "if alcoholism is a real thing," Moore writes she began drinking, thinking Kutcher wanted "the girl who could have a glass of wine at dinner, or do a tequila shot at a party." She explains: "I didn't think, This is a kid in his twenties who has no idea what's talking about. I didn't think, I have nearly two decades of sobriety under my belt, and that's a huge accomplishment. Instead, I cast about justifications for his argument."

Later in their marriage, Moore notes that Kutcher became "less and less present," and Moore found herself going "into contortions to try to fit the mold of the woman he wanted his wife to be" in an attempt to save her marriage, which she said included threesomes. Moore said the act of opening up their union brought with it "a totally false sense of power," and called it "a mistake."

The end of the relationship: Overindulging, infidelity

About 18 months into their relationship, before tying the knot, Moore and Kutcher were expecting. Tragically, Moore miscarried at nearly six months, which "decimated" her. She thought because she was drinking and smoking when she learned of her pregnancy (and smoking a few weeks after) that it was her "fault." She leaned into the drinking to cope with her pain.

She explained on "GMA" the depths of her pain when the two were unable to conceive.

"I can’t even bring fully to words how lost, empty, desperate, confused (I was)," she said. "I really lost sight of everything that was right in front of me, which is the family I had, and I think the weight that it put on Ashton. It’s kind of a natural thing to pull back when somebody’s clinging too tight.”

Moore writes of a time when she nearly drowned in a hot tub after a night of heavy drinking in Puerto Vallarta, Mexico – a trip in celebration of turning 45. Moore says Kutcher was "furious." Following a detox from Vicodin she abused after a dental surgery, she said she felt like she'd "lived through a war" and received no "compassion" from her husband at the time: "I felt like he was angry with me for having this problem in the first place: You made your bed; now you have to lie in it."

Moore writes of two of Kutcher's alleged affairs, the second just ahead of their sixth wedding anniversary, which appeared to be the final straw. He moved out in 2011, and she released a statement at the time that said: "As a woman, a mother and a wife, there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life."

USA TODAY has reached out to a rep for Kutcher for comment.

On Tuesday, Moore acknowledged the excruciating agony she felt following their split stemmed from more than just their demise.

“I really know that there are parts of what occurred with this relationship ending that were a level of devastating for me that was really just about that relationship, it was really about my whole life," she told Sawyer. "It was about being the 2-year-old who wasn’t safe, that this really represented that I’m not lovable, that I’m not deserving, and that’s not about him. That’s all just about me.”
