Personally I believe:
Some people prefer to see the narc as evil, rather than the truth, which is, they don't give a damn about you, your wants, or your feelings. Using you and not caring about you is not the same thing as evil.
It may FEEL like evil to you because you want more.
I also don't believe too much in ST.
Again. I believe that calling it ST is a comfort to you.
Pretending he is away to punish you, when the reality is most of the time, if the narc is not with you he is doing something else. Narcs require supply.
Sure they may pout for a few, though not nearly as long as you think they do.
Most of them have a big smile on their face as they are texting OW while storming out of your house. That would be a more accurate description of what they do.
