25 - that must have been a difficult line of work.
It is hard for me to imagine anyone sexually abusing a child, which is why I tended to give my FIL the benefit of the doubt. My W works at keeping a relationship with her dad and talks to him fairly regularly. He was invited to all our family functions.
Her sister and 2 step sisters have no contact with him. Her younger step sister in particular has called him "Creepy" and said that she did not want to be around him, and would not bring her friends to the house.
My W would limit contact with our kids and her dad, but I think it was done to appease her mom, and not really out of concern for our kids safety.
All of this happened long before I ever met my W, so I only hear stories. I have no idea of the truth.
