It's great that you said to relax and figure it out together.
Make it sure that you will love each other and respect each other no matter what you 2 believe.
Spirituality might be a life long journey or search. Even with an atheistic or agnostic view you can be spiritual.
Belief in a God or a creative power can be separate from JW doctrine or bible doctrine.
I don't believe in the bible's description of god anymore, but I didn't give up faith in a higher creative power, who created everything in a way, that natural processes could develop life (for example by evolution).
I wish you 2 all the best.
