There is no such thing as "the one" - belief in itself is harmful to a relationship. Romanian-born psychology expert Francesa Tignian posted a video on her TikTok explaining to 1.3 million followers why giving too much importance to your partner can eventually lead to a toxic relationship.

"It's dangerous because it creates a false belief that you just need to find the right person and then everything else will fall into place," she said. The belief that happiness starts when you enter a relationship creates exactly the dynamic of toxicity.
