Awww man GH, I am really sorry to hear about this for you....obviously as our sitchs are eerily close, this has really taken me aback. If I were closer to Fla I'd come down and take you out for a drink (well, you could be the Designated Driver and I'd drink )
In any event, I really feel that this is something that you will have to confront your W with for a variety of reasons....but I also beleive that you will need to have your emotions in check before doing so. Give it some time to settle and move forward from there...you don't want your negative emotions to run the conversation here...you need to be rational and sane. This is something that both you and her will have to come to grips with before moving forward.
Now, I could say that perhaps the test was for other reasons, but as AmyC said, given recent history, I don't seem to think so. This sucks in many ways for you, but you always sorta suspected it...
In the end, you will do what you believe is right for you and your R. I wish you luck in anything and just know that you will be in my thoughts today. Hang in there.
Best,
Rob
