My 6yr old came to me with her dad ipad which he let's her play on showing me porn nothing horrific women's boobs basically but I then went into the history to find he had been looking at other sites that weren't so tame. I then accessed his Facebook messenger to read messages he sent to other women saying about their nice smile lovey eyes etc. I'm numb. I know I shouldn't have looked but now I don't know what to do.....any advice ?
