Nope. Leaving is actually always easy. You also NEVER know what comes next. Even staying and working with a flawed partner, who may not even realise how controlling their behaviour is, is a tougher choice, and not an always wrong choice. You seem strongly invested in narratives of irredeemable extreme narcissistic personality disorders, which are very rare, and even as a disorder there are people on the milder ends of the spectrum who can be helped not to be so controlling and steered away from manipulative behaviours. Sacrificing absolutely everyone's perfectly navigable relationships just because there are some people some people out there that are psychopaths is too severe a point of view to count as an LPT.

Be cautious of blanket advice like this. A partner who desires that you spend a portion of time together just as a couple is not necessarily doing it for control. A partner who can help you recognize toxic influences from your family or existing social circles and wishes to help you get away from them can be a very good thing. If you are losing touch with friends and feeling isolated, then definitely conversations need to be had, and counseling may be necessary. A good partner will be open to it and accept that the relationship may need rebalancing. If those conversations are fruitless, or counseling is rejected then consider Ging TFO.

That won't make anyone happier. It never does. The fact that someone who has dabbled in the far right now sees it as misguided makes me happier. Your life can have a positive meaning if you want it to, that meaning is your choice to make.
