My daughter and son has been a victim of sexual abuse. my daughter's father was looking at phonography on his cell phone, and masturbating in front of them. Also after my daughter father finished, he put his fingers on my son nose. The second occasion is when my daughter visited with her father for a month in Virginia. He also performed the same sexual act, and also was sleeping in the same bed with my daughter; she was only seven at the time. he kiss her arm sexually. she was screaming. When she would call me she asked me not to tell him that she called me. he also was touching her breast sexually, and he also was indulging in drugs such as cocaine and alcohol. he also is a child abuser. I really trusted him but what can I do. because know one contacted the cops.
