Asherraa,
I am a single older gentleman. In the past my friends would arrange to have me over to meet one of their single women friends. I almost never experienced a situation where they didn't ask me where I go to church, sometimes before they knew may name.
I had a few relationships that lasted a short time, but they have always flopped eventually. Even if they don't start out asking me where I go to church, once I get to know them they want to take me to their church. I always refused the invitation. They always wanted to know why I wouldn't go with them to church, so I told them. That was usually the last time I heard from them too, and I was not unhappy. I always said good riddance to a lot of needless turmoil. Since then I met some freethinkers back home and we get along fine. I never have to explain a thing.
I guess what I'm trying to say is this, you can't make someone into the person you want for a companion, and you need to meet someone who already is that person.
