Whew Sheila - that's a lot. First off... you should be incredibly proud of your son. He sounds so mature and self-possessed.
Second, I'm sorry about your conv with your H. That sounds so stressful and demoralizing. Are you two simply at an impasse where the OW/work issue is concerned, or does he flip-flop on the issue? Agrees when it's convenient, disagrees when that's more convenient. Do you get the sense that he is past OW so doesn't understand why you aren't? Has he done much reading on rebuilding marriages after affairs?
And you know you are definitely in my prayers. Get those tests sorted out and hopefully it's minor.
