OP- after reading all of your replies to people, and your agreeing with or disputing of other's posts, I just want to say I think you already know how you feel, and where you are. I just think you are afraid to admit it, even to yourself.
You don't have to put it in a box with a label. But if you need a label, it's okay to say "I'm agnostic". It's okay to question the existence of a god, or to not believe in one at all" It's even okay to believe in a god that doesn't fit any criteria of a specific religion. Believe in your own god if you want.
I currently refer to myself as a free thinking agnostic. I don't believe in the Christian God. I tried, but the more I learned, the more I realized (for myself) it was all a fallacy.
Admitting it to dh, was difficult, but by the time I did, he already knew I felt that way and was okay. He is still very much a believer, but at the same time, he is so far (more open and accepting of different thoughts/beliefs) from his stiff CoC upbringing. He's changed his mind over the years, and realized things he was taught, aren't the absolute truth.
Hugs. I've been on your journey, and as others have said, there is such a peaceful feeling when you reach your own acceptance.
