The '5th Wave' actress was devastated when her father "just left" her mother when she was a child and she admits their separation had a huge impact on her.
She said: "It made me harder on myself. [It] was as heavy as you can get to dismantle a family, for sure.
"When you're betrayed by someone that is a bloodline, you start to beware trusting people and to protect yourself at all costs.
"For a long time, I did that too much. I wasn't letting people in."
The 18-year-old star also admitted that, when she was 16 and filming 'Carrie', she felt incredibly insecure.
She told America's Marie Claire magazine: "I felt fat; I felt not pretty.
"I felt like I didn't really know who I was. I was so confused; I was scared. I had bad acne. I felt incredibly insecure."
However, these days Chloe is much more confident in herself.
She added: "I'm so free now. I don't know what happened, but when I turned 17, this huge weight was lifted off my shoulders.
"I don't worry about what people say about me. I know who I am, who I want to be, what I want to portray myself as, what I want people to think of me."
The teenage starlet insists she's not interested in a relationship "for a while" and has no desire to date anyone older than she is.
She said: "I don't want to date older people, because I'm 18 and older people are more serious.
"Then I kind of realised, I'll go on dates, why not? And that's kind of how I am right now."
