You asked about premarital classes that are nonreligious. We are actually going to premarital counseling with a therapist. We are talking through all those things that my religious friends have done in their church classes. I'm really enjoying it and I think he is finding it helpful as well. At first I was hesitant to go to "counseling" when our relationship is good- what if there was something looming wrong we didn't see or what did that say about us going to counseling before even getting married? Now it's turning out to be really great and has actually made us realize we are 100% perfect for each other.Anyway, just a suggestion
