One of the msot helpful things I learned in therapy is that human brains love stories and they hate to be bored. So my brain (and it sounds like yours too) will make up stories and then we get all worked up over something that hasn't happened yet and might not ever happen. Our brains don't care if the stories make us unhappy, they are just glad to be entertained.
I learned to get a lot better at stopping my brain when it went off on one of these stories of things that hadn't happened yet but might happen. It helped me a lot.
This is one of the reasons GAL--especially if you are doing new things--is so helpful. It gives your brain some entertainment that doesn't involve raking you over emotional coals.
Don't worry about board statistics. In your situation, you don't know your wife is having an affair yet. If she is, you will eventually know for sure, but until that happens, don't go borrowing trouble you don't have yet.
Focus on GAL, becoming emotionally healthy, being a great parent.
