Concentrate on your own recovery right now. I hope you feel much better soon.
You are, as everyone keeps telling you, not the unreasonable one in this turmoil.
When you feel strong enough to mention the matter to your daughter then will be the time to find out what you want to tell her.
I know what I would want to say - "self-seeking, uncaring besom" would be the least of it, but that would of course ruin any and all hope of a future relationship with your daughter and her family.
Please do remember that if you had just let them come to your house knowing full well that they might be infected, you would have felt dreadful about not having asked them to take a test first. They refused your reasonable request and now you are paying for their inconsideration.
