No. My husband and I both see the benefits of reading/participating in this forum, luckily.
Do you think it would be useful for him to take a look at some of the articles or some of the threads - some of the things that might be useful for him to understand about PTSD for example and how this forum, as a result, helps you? That interaction with others that are in a similar position, is helpful? It's not that you're doubting his support, but unless he's walked in extremely similar shoes, it would be difficult for him to understand what it's like to be 'you'....
Just a thought :)
