If you're talking about HPV, I get it. Usually I say 'understand', but 'get it' is probably more appropriate here - W tested positive for HPV twice, 12 months apart, after 40-odd years of monogamy.
A couple more thoughts -
1) It sounds like the refusal of the poly is not a deal killer for you now. Therefore, don't make it the subject of an ultimatum, because if he calls your bluff, you'll lose a lot of power.
2) What happens if there are other As? Will you D? Or will you push on with R? If you're likely to push on with R, I think something else may be behind your desire for a poly.
For me, BTW, the HPV brings out anger, sadness (because it makes me fear sex), and fear (of HPV-induced cancer 13 years from now). What feelings does the STD bring up for you?
Of course, if another A is a deal killer, then my point here is moot.
3) I also understand the importance of honesty, and if you say you just want to know the truth, I'm with you. Telling the truth was the prime way my W showed me she was remorseful.
Have you considered telling your H that the truth is important. In other words, you're not looking for more reasons to beat him up; you just want to know what actually happened.
Have you asked your H why he objects to the poly? If he says something about you not trusting him, I wonder and hope he'd come around if you said something like, 'Gently, H, you lied for 7.5 years about your A, so I can't trust you right now - but the poly would help build trust, and that's why I want you to take it.'
If things don't add up for you, it could be paranoia or long-lasting shock, but it's probably signals he's sending out. If you sense that he's not coming clean, you're probably right.
I guess the problem is that there's no legal way to force anybody to come clean, so your sitch is objectively very difficult to be in, which brings me/us back to the 180 - it can help you be strong and make the best decision for you, even though he's being less than totally honest.
4) Thanks for the kind words.
Again, this is a very difficult sitch, so don't beat yourself up for having to work hard to decide what to do.
