I was hoping we would both tell him together, but it appears H broke the news last night while I was at a friends house.
DS1 was sent home from school sick today & on the walk home he suddenly said "I know you & daddy are going to live in different houses soon"
I was a bit taken aback & asked who told him, to which he replied "Daddy told me, he said it's because you both want to be rich like nanny & gaggy." (Not sure where that came from!)
I asked how he felt about that idea, & he said "Okay, I will be able to sleep at your house & daddy's"
I am relieved he seems to be taking the news quite well, as I was worrying a lot about this, but I feel a bit angry that H didn't let me know he was going to do this.
