Interesting article; of course it made me reflect.
What I see in that description is what my H has been during this crisis, it really wasn't him at all before. And my H is quite an avoidant, especially of conflict.
Like the article says, we all do this to some degree, but generally we keep it under control. Like so much, in MLC it gets OUT of control, and is allowed to take over.
It suggests straight talking as the only remedy, if there is one; I tend to agree. What happens with us as LBS is that the fear takes over, yes, it does, and that keeps us from the straight talking. That isn't to blame us -- it is natural. It's just what happens.
I've found that every single time when true straight talking is possible then it always diffuses this passive aggression, it's just that true straight talking isn't as simple as it sounds.
Of course, I also see where I have, not necessarily consciously, showed some passive-aggressive behaviour when trying to avoid or stall some MLC madness.... it's not easy to keep a clear head and understand when just not doing anything even if we said we would is "being still", and when it isn't right...
As with so much, we can learn from this.
