I banged a barmaid that was wearing a crucifix once. She mentioned God several times during the interaction.

Yes, I have. She was deep into Christianity and didn't like the fact that I was not. She said stuff like "unless we can be "friends in Christ" we can't have a relationship. She said she prayed for me all the time. In short she thought I was "lesser" because I didn't share her beliefs. OK, I get that.... and walked away.

Yep, my ex wife was a catholic (I'm atheist) . She had 3 big religious statues in the house (~ 16 inches tall) . I loved her and accepted & respected it (although, I did secretly hope for an earthquake to break the statues).

Much to my surprise, after years of marriage, I discovered that she had broken commandment 7 a few times with a few guys, then we were done.

That's it in a nutshell I guess.

It made things even more complicated.

Dated someone for 8mos. But his obsession with geezus proved too much to bear ...

It become increasingly difficult for me to believe that he believed what he believed ! Dismal outcome.

Never again.

Last partner was Christian became more involved after separation

When I was 30 I fell in love with a 24-year-old Catholic. She was bright, funny, and very sensual. Her Catholicism was deeply embedded in her. She talked about becoming a nun one day, but was exploring her sexuality at the time. She didn’t try to convert me, knew I was Jewish and didn’t believe in Jesus Christ, knew I wasn’t religious, I didn’t attend synagogue or anything. Our religious differences didn’t affect our affair. We drifted apart when she went off to graduate school out of state. I’ve tried to find her over the years but I’ve had no luck.

Yes. But they weren't really active or practicing.

I dated a Lutheran (which I feel is just another way to say "Catholic" )  back when I was in high school. Back then I had no strong feelings about religion one way or the other. It didn't matter much and I understood why she felt so strongly about it, as her father was dying from cancer. Good christian that she was, the reason we didn't work out was simply that she had slept with more than a few people I had considered close friends.
A few years ago, I entered into a relationship with a girl claiming to be "spiritual but not religious". She apparently felt that I was extremely skeptical (which anyone on this site would likely find quite laughable), too serious (coming from someone who never held a job in her life), and highly paranoid (from years of runins with law enforcement).
I think it was Sigmund Freud who said that girls are most attracted to men like their fathers, and boys to women like their mothers. Strange, really, because while I find my mother to be practically intolerable because of her religious views, "good christians" is all I seem to be able to attract.

Oil and water do not mix. Over time there will be an ever escalating pattern on both side relating to belief and worldview.

I have found that the following points should be completely discussed and an agreement formed before any committed relationship.

Belief system ( or lack of belief )
Worldview

These first two points have a huge impact on last four

Money
Friends Family
Children
Sex

Discuss it up front and set it in an written agreement to avoid litigation, wallet, and heartbreak later

i am a jewish atheist. my guy is a jewish (but not especially religious) nonatheist. i hesitate to call him a theist because while he says he believes in a god, he can't describe that god, and expects nothing from it, and doesn't act as if that god expects anything from him either. when pressed, he finally told me he believes in a god who created evolution. he won't say more. he's never read a bible. he's not completely easygoing about it in that he hates when i mention that i am an atheist. i can shut him up by murmuring "talking snake," although i first had to explain to him what that meant, as (remember) he has read no bible of any kind.

g

it was good why all these dumb questions many ppl that are opposites get along they enjoy what the share and don't discuss what they don't they just love each other
