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?

First of all, let me say that it is indeed quite shocking and if you were me, I would have immediately left him. However, this is a serious issue and needs to be dealt with maturely, even if it means talking to your husband and finding out the real reason for this heinous act. Please give him the benefit of doubt for the sake of your family, if nothing else. You could also counsel him into speaking the truth and finding out if he's a Paedophile or not. If he agrees to being one, I advice you take him to a psychologist immediately or a counsellor who would be able to handle the situation in a mature fashion. Hope it helps.
