To answer your questions:-
Q.1. I left and my marriage is still in tact.
Q 2 . " are we both happy? if you mean in our religiouse relationship, our last fight was over the noice she made from the vacuum cleaner as I watched T.V. That may seem a silly comment but we both realised it was more fun than arguing religion.
I hope you can instigate similar arguments, so your man realises a good husband has house hold chores that are more important than religion.
Wish you the best.
