Good topic, Azzy.
I think this is the most special of partnerships, and I don't necessarily mean special in a positive way because it's not always so.
But I believe the partners should be as open as possible and try to be decent in their approach to issues.

It doesn't always work. But no matter what the kids should never be witnesses to battle nor should they be pawns or bargaining chips.

But what would you prefer, the painful truth or not being aware of the truth because it's more tranquil that way?
