Interfaith marriages can work. But they take A LOT of work. I was raised Protestant and married a Muslim. When we married, neither of us was particularly devout. Neither of us converted, and we just "accepted" the other's beliefs. When we had kids, the plan was to raise them knowing both religions and let them decide for themselves when they felt ready. In the end, after our boys were born, my ex decided since they were "his sons" they should be raised in his faith. I studied Islam quite extensively, and became the "go to" parent when my boys had questions b/c I understood it from an educated viewpoint whereas Dad only knew what he had been told growing up. And, yes, I said "ex"... we were married 29 years and have been divorced for a year now. Did religion play a part in our split? No, not at all.

It certainly doesn't make a marriage any easier when you don't have common beliefs, but it CAN be done. I do not think anyone should convert for someone else. One should only convert when one truly believes another religion best serves their idea of the truth and the way to salvation, IMHO.
