I was unable to make it work. My ex is very committed, to the extent that her religion took first place, and rational discussion of her beliefs was impossible. Perhaps it can work where the religion in question isn't quite so demanding of exclusive devotion. Obviously people are all different, some other atheists could perhaps be more tolerant of magical thinking. Not, however, this particular atheist. I just can't bear it, much less respect it.

Yes, but I find it difficult. The key is for each one to respect the others beliefs

Of course, so long as they respect each others views. They have more in common than they haven't

This question reminds me of this episode of Seinfeld.

I have am friends with a married couple who cheer rival college football teams (OSU and Michigan) and they make it work, so... It seems possible. Didn't work for me, but we had other, bigger, problems.

I've seen weirder combinations in love but why would any Atheist want to be with a Believer?
