No. While it’s fine with me for my partner to hold religious views (although to be honest, I probably wouldn’t be with them to start with because I think people who believe in any kind of superior being have some kind of mental deficiency), it would be on the basis that they never, ever, ever tried to convert me - I would’ve made this very clear right from the start. They could go to their church any time they wanted, but they should never come home and tell me any of that god nonsense, because every time they did, that’s another bit of my esteem for them chipped away. So, for them to say they wanted to marry me, but only if I go against one of my deepest held beliefs, is wrong on every level. To me, it’s the same as saying I would only marry them if they became an atheist - something I would never do. I couldn’t respect anyone who would ask that of someone. And if they made it an ultimatum, then I’d be getting out of the relationship.
