I agree he really likes her, but he also said he doesn’t want a religion with a lot of rules for himself, so something like that. She is deeply involved in her faith which does, as I understand it, has a lot of rules. This isn’t something she can compromise and still be in good standing with her faith. Would he be willing to have any kids raised in that religion? And while she might not pressure him to personally change, how would he be expected to behave in front of the kids, e.g. no coffee or colas?
