A relationship expert has gone viral on TikTok, telling viewers to watch out for seemingly innocent phrases if they fear they are dating a narcissist.

Cory Skolnik, who resides in Las Vegas, has racked up millions of views with his multipart series, saying there could be sinister alternative meanings behind phrases such as “I love you,” “She’s just a friend” and “I’m sorry you feel this way.”

In most relationships, declaring love reassures a partner, but if uttered by a narcissist, they could indicate that they are controlling and/or cheating.

In his first video, Skolnik states that if a narcissist says “I love you,” what they really mean is: “I love owning you, I love controlling you, I love using you. It feels so good to love bomb you, sweet talk you, pull you in and then discard you whenever I please.”

Dozens of viewers took to the comments section of the clip, claiming that they had dated “controlling” narcissists who frequently weaponized the phrase, just as Skolnik had stated.

“100% true. This sadly describes my ex,” one sad singleton said.

“This hits way too hard. I’m so happy I just got out of this kind of relationship,” another commiserated.

In a second video, Skolnik theorized that if a male narcissist utters the phrase “She’s just a friend” to his partner, it’s more than likely that he is cheating.

“Translation [or what he really means is]: ‘I keep this person around as a backup for whenever I get bored. They may replace you if you leave. In fact, they may already be acting as a valuable side piece to me,’ ” Skolnik said.

Again, several singletons left comments claiming to have been victimized by the phrase.

“I almost threw up with how accurate this was,” one jilted person remarked, while another added: “This one hit hard and true!”

Skolnik shared further videos, revealing what he believes are the real meanings behind other popular phrases — if they’re uttered by a narcissist.

For instance, the dating guru believes “I’m sorry you feel this way” actually means “Sorry, not sorry. Let’s get this argument over with already so I can continue my abusive behavior in peace. I’m not sorry I did what I did, I’m sorry I got caught.”

Meanwhile, Skolnik says “You’re overreacting” indicates that “you’re having a perfectly normal reaction to an immense amount of BS, but all I see is that you’re catching on. Let me gaslight you some more so that you second-guess yourself.”
