A travel to Mactan island

I have traveled to Mactan island one and a half years ago. I met a girl who is eleven years old when I was walking shore near the hotel I stayed. She was selling souvenirs and said that she didn't go to school. Her parents divorced and her father left her and her mother, she said. I wonder that why they could divorce although filipino can not divorce. However, she and I are not good at English, so we couldn't communicate more.
