Welcome!
But wow what a but! This is the toughest question anyone has asked here. My brother is not a believer and his wife is and they do fine together and have for years.
I guess part of it is going to depend on your wife's views. Is she simply worried about your soul? If so, in spite of what some of the so-called Christians here say, it doesn't appear to be sure that anyone knows for sure that God will not admint a good person to heaven in spite of unbelief.
If your wife truely believes in the new testament God of love and forgiveness then she may be able to find a way to see that you can be on the same track as her but without the firm belief in a God.
In fact, anyone with a reasonable theology will understand that
no one can claim to know anything about God at all. He really is not something that has to be truely comprehensible to us. He really does, as many are fond of saying, "work in mysterious ways". For most of use "agnositic" is all we can really be. We may choose to believe one thing or another but that is
not the same as knowing.
As long as your character is one that isn't opposed to the values and morals that she holds to be important then she must trust this God of hers to accept you for that.
There are a lot of different kinds of "Christians" it seems. I hope she is a kind that can be compatible with your world view as long as your values are compatible. I was very happily married for 20 years. I wish the same for you.
Common sense isn't
