So i just found out my boyfriend was done for............?

possessing indecent images of children where the pictures were rated between the ages of 13 to 18, he says hes sorry and it happened 5 years ago and hes was also on the sex offenders register for 7 years and has two years left on it, he's so sorry for what he's done and i have been with him for two years. hes a good guy, hes polite, loyal, caring, intelligent and safe, but what hes told me is a bit of a shock for a guy who went to church when he was young, hes 31 now and I want to continue the relationship, but wonder what you think of him? if you were in this situation what would you do?
