Can't date regular people? Hell, they can't even date each other. My wife and I were both converts (we met about the time we got baptized). Having been "out in the world" we knew what dating looked like. This led to counsel about spending too much time together alone. I don't know how you're supposed to learn anything about somebody you can't even have a private conversation with.
We've been married a bit more than 44 years, seems to have worked out OK.
