That is definately the crux of the issue - if you are each sucking up the others dysfunctional mood then who will provide hope for a brighter day another day? It takes an ability to step back and take stock of how IHJ really feels, maybe even go take a moment to yourself to regroup so that you can be the one to suggest the silly penguin movie and if he grouses, won't watch you say, "Ok, well that's what I'm going to do."
