Well my husband is atheist and I am a christian. I cannot speak for him on the reason he is atheist, all I know is that it doesnt have an impact on our relationship or our children. I go to church EVERY Sunday and take the kids with me. Hubby says when kids have parts in a play or what not then he will come to see the kids. I did have to lie to my Grandfather when we got married cause Grandpa did the ceremony, and if he knew he was atheist he wouldnt have done the ceremony.
