Maybe its in your earlier posts (which I haven't read, admittedly), but why are you guys talking to the kids about this? Your H is WAY out of line for dnagling this in front of the kids. And, I am not sure why you are bringing this up to S on the walk last night.
Let me know if I missed something (which is entirely possible). And if I missed it, I'm sorry.
But I see nothing but harm (to the children) from ANYONE discussing something that may or may not happen.
My mother (who is on H #4) did this to me growing up, and I can tell you it had a he!! of an impact on me, and NOT in a good way.
