My world has come crashing down when i found 100's of child porn images on my husband's laptop. We have a beautiful family. What should i do?

100's of child porn images -> How young do those children look like? The term child is different to everyone -.- If they are infants and below 12 years old, he has a serious problem. If they are just 18... which some still consider children... then maybe the problem is not that serious.
