How to comfort your girlfriend when she's scared?

My girlfriend is scared of me she's scared for me to touch her. She was watching a documentary on this girl who was abducted by her step father had 9 kids with him after being raped threatened forced to marry at a young age it kind of traumatized her. She doesn't want anymore kids now she has a son from a previous marriage he's 11. What kind of dad or step dad has sex with their own kids and married them especially if they're under 13 that's sick. I'd never do that to my kids or my step kids no wonder she's terrified she said she doesn't trust anyone not even me I been with her for 2 years. How did this girl survive being kidnapped at 12 being forced to marry her step dad by him and having 9 kids seriously how does a 12 year old have a kid I'm sick im upset about this too. She should stop watching this true crime stuff if it bothers her but she's obsessed with it even though it bothers her. And how did this kid survive she said she was close to being shot several times by him. I dont understand why men kidnap and rape young girls it's just not right let kids be kids dont hurt them this is really sad. Why can't people let kids be kids anymore. How can I make her feel better? Is it ok to cry in front of her?
