(it also makes me wonder if perhaps we should have a companion site here where some of us LBS can match up with each other...)
As to advice. Your last paragraph is where I am at mentally. I know it's a marathon. I know it's complicated but I still hope for the quick fix. Realistically there might never be a fix. I also thought things would be better. Despite knowing better I still see each step forward as progress and with each step back I get hurt again.
I do think in YOUR sitch insisting the kids don't see the other R is fair. And you SHOULD have some control over that.
