There's a difference between someone who's full of themselves and someone who's quietly dangerous — but when you're in the thick of it, that line is incredibly hard to see. Narcissists can be exhausting, sure, but sociopaths play an entirely different game: They don't just crave admiration; they exploit it.

The good news? People who cross that line always leave clues. Very specific ones. Once you know what to look for, you can spot the shift from self-centered to sinister long before the mask slips.

People who cross the line from narcissist to sociopath always have 3 sinister tells:

1. They weave a tapestry of lies

If they were a true narcopath, there would have been warning signs at the very beginning of your relationship. The sociopathic side of the narcopath makes them masters at deception. For instance, they may have lied about their job, finances, or family. They probably didn't have close ties with too many people.

A sociopath has little concern for another person's feelings, desires, or needs. Their primary purpose is to get what they want, regardless of how it may harm other people. They were probably very charming and charismatic, which is how a sociopath will win over the love and affection of their target (you).

They knew how to play the victim, so nothing was ever their fault, and they had a way of twisting it around so you believed it was somehow your fault. A sociopath continuously invents outrageous lies about their past experiences and other people.

They believe their ability to lie and use logic is exceptional, yet a study showed that intuitive thinking can detect lies easily. If your ex is a narcopath, you'll see a history of their fabricated storytelling and wonder how you could have ever believed some of those absurd lies in the first place.

2. They find reassurance by breaking boundaries

A narcopath will be thoroughly satisfied with their mental attributes and their physical appearance. Narcissists are vain and selfish. They need approval and praise from everyone around them and will be set off by the slightest criticism they receive. Studies of narcissism helped explain how criticism can not fit into their sense of grandiosity.

Much like a sociopath, they'll have no remorse over hurting people. Because they have no conscience, they may be successful in a business where cut-throat behavior is essential to get ahead. 

The narcissistic side of the narcopath will find ways to punish those who reject them. They constantly seek validation from others and often put down others to inflate their ego. They are addicted to the spotlight and need to be recognized for every achievement.

Because narcopaths need constant reassurance, they're more likely to become desperate during a divorce. They won't honor boundaries — They are willing to break laws and hurt others, regardless of the consequences.

3. They exploit others just to see their reaction

A narcissist needs to be validated by others, while a sociopath doesn't. A sociopath will exploit others because they find it amusing, while a narcissist only exploits those they believe are a threat.

If you're dealing with a narcopath, stop playing their games. They enjoy pushing your buttons just for the fun of watching you squirm. Your vulnerability to exploitation is probably more likely than you think. Researchers found that men with higher levels of psychopathy had "a better understanding of the personalities of people who are vulnerable to exploitation." 

If you're dealing with a narcopath, don't feed their ego and avoid falling prey to their traps. Even if your ex isn't a narcopath, going through a divorce wreaks havoc on your emotions. The person who remains calm and collected usually has the upper hand during divorce proceedings (not to mention relationships in general).

During this time of turmoil, you should consider scheduling an appointment with a professional who can help you vent your frustrations and make rational decisions.
