I don't mention it. My dBPDbf once opened my laptop that showed a post on a local forum. He was a little upset and very ashamed. He has accepted some parts of his condition, but it stills hurts him to hear he needs to be treated different than others.
This afternoon I gave him an example of two similar events that had very different outcomes because I responded differently. It was meant to be a positive 'we will find a way to dot his' message, but again he felt ashamed. He wants to be normal.
Telling him I got the input for my altered behavior from a message board dedicated to discuss 'people like him' is too much. He knows I read about it, I just don't tell him where.
In cases of undiagnosed SO's I'd personally stay away from mentioning this. I don't think any good can come out of it. I think there's a thread somewhere on how to mention to your SO that you have suspicions in a way that reduces the chance of immediate resistance.
