As a victim of former childhood sexual abuse and mother to a 2 y/o, I feel absolutely sick right now and if I were you, I would leave him...Now. Then, I would call the police & have him dealt with. But, that's just me. I'm the one who took my grandfather to court when I was a kid & was disowned by my entire family for over 16 years. But, at least he never had a chance to hurt anyone else & I can rest easy knowing that!
