'I wanted to set an example for my daughter; That was something that changed for me. One day I said, 'What am I doing? This is not right.' I would hate for her to ever be in this situation,' she told the Star.

“At the end of the day you have to do what's right for you. No matter how many promises people make or anything else, when they show you who they are, believe them. Because you can't change people.'

Simone also said she was content raising her baby Zia, six months, alone and she believes she made the right choice.
