Well, I had an awesome visit with someone yesterday, so when the dad I arrived I broke the news....even without confirmation that the other one would take the place. If it's not them, it'll be another "normal" family. No more procrastinating. And I knew that if I didn't do it spontaneously I'd be awake saying it over and over in bed all night. I wanted to sleep And I did.
Now I hope the other one confirms today. Or I keep looking. Water under the bridge. Thanks for the nudge I needed to make the decision!
