40sw I don't really feel like I have enough information here. What I'd like to know is in what ways this was supposed to be "wrong". If we're talking general religious qualms... while personally I have a policy of not encouraging people to break silly religious taboos, neither can it be your job to help him keep them if he is not so inclined. As
imalion might say "It's not your monkey." I find it to be a little creepy to be involved with someone who is acting against their stated values, myself, so I'd probably try to talk to him about them, and see if there's anything that can be done to help him find a resolution. (Or maybe this is a way for him to dramatize the whole sin and forgiveness bit?) You are both adults, and while there are innate complications because of the nature of the relationship, adults should be able to navigate these things. (Which of course also includes the option of saying "gee, maybe this is more than I want to deal with".) But are there other people who are in line to be hurt? That would having me taking a big step back...
