When you find something, do NOT bring it up immediately. Let it sit in your head for a few days, and see if it will do any good at all to bring it up. A month or so ago, I found the paperwork where ex- was trying to get ex-OW in the country last year, that he supposedly proposed (I expect they really just talked about it as a way to get her here in the country).
I wanted to escape the apt. immediately once I saw that. Then I wanted to say something. But I haven't. I posted it here, and that was most of anything I did. Thank goodness. There is nothing much good that could have come out of me saying anything.
Your H is with you. I understand that you will be vacationing where she went too - but you can give him newer, better memories. Do that! And don't confront him on ANYTHING right away. I'd say always give it a few days so you can decide if it's important. By then you might decide that it isn't. And if it is, you hopefully won't be accusatory - the immediate emotions of finding something should have passed.
