With condom use and in the absence of an outbreak, the risk to the wife is tiny. She probably weighed up that tiny chance of transmission against discrimination against her based on flawed science and taking that tiny chance won. Again, I'm not saying it is right, if I had a lifelong STD I would disclose, I think, but I can understand the "lesser of two evils" logic.
I don't actually know if I've got hsv. The last test I had was negative, some time ago but the NHS only offer tests in very specific circumstances now. I've never had anything that resembles an outbreak and neither have my last few partners, as far as I know. I can get a test privately, but I really don't see the point. It doesn't make scientific sense for me. I wouldn't change my sexual practices if I did have it. I know my current partner wouldn't want to start using condoms again.
