('Nofights' here)
Jaded and Echo
What I learned from the goings-on at N-partners was an extension of what I learned from the experience with my N. That when I see certain behaviors in another that are not acceptable, I do not try to change the other, or argue my position with them. I merely announce my position and move on. When I broke up with the N was the first time I ever broke up with someone and did not agree to any discussion of the causes, because we were obviously on 2 completely different wavelengths (little did I know . . . )
That's how I have handled the first such breakdown at n-partners (over a year ago, and repeated at least 3 times since), and I have done the same recently when an N appeared in a sports league that I belonged to. I spotted the unacceptable behavior, I announced my observations, and I moved on. I am finding it healthier and more satisfying than trying to stick around where unacceptable behavior reigns. And I don't carry lingering worry of whether I did or didn't do the right thing because I know what I saw and that is all that matters to me. That's an improvement over wondering if other's views are more 'valid' than mine, etc., which leaves one vulnerable to manipulation.
It obviously depends on what the issue is. I am not advocating 'my way or the highway'. But it has all taught me how to better identify certain issues that cannot be compromised (boundaries, I guess), and to not doubt myself on them, which hopefully makes me less of an n-target in the future. In the case of Sand, what I spotted in the first conflict was a severe double standard, and I view that as a personality trait that you cannot 'argue' someone out of, so why bother yourself with it (thus the 'nofights' handle). I stick with the generally accepted description of N-ism, and I can't say that sand has demonstrated to me that she is an N. But she has demonstrated to me enough unacceptable behavior for me to want to move on and not be affected by her positions.
There are enough times when I have no choice but to accept it, specifically in the work environment, that I will not tolerate it when I don't have to.
Hope that addresses your posts
