I would also look for solid evidence of a affair, lots of red flags in your posts.
I agree with Coach on this one. I saw many of the same red flags in my own sitch, and ignored them for a a while. The A was there, I was in denial.
Although there is some discussion about it, I am pro-snoop, pro knowing about the A, and pro exposure. If there is an A, you deserve to know about it. You deserve to have the freedom to make informed choices and act with the knowledge of what is (or is not) going on, rather than what might be or might not be going on.
