Tell her 💬
Telling your best friend is the move most relationship therapists and friendship researchers advocate. Studies from UCLA's Shelley Taylor on the 'tend-and-befriend' response show female friendships often involve high levels of mutual disclosure and protection. A 2019 University of Tel Aviv study found friendships last 7 to 10 years on average, but trust-based ones can endure a lifetime if honesty is preserved. Telling protects your bestie from a deceitful partner before deeper commitment (engagement, kids, shared lease) and demonstrates loyalty. Reality TV examples abound: Khloe Kardashian's friends warning her about Tristan Thompson, multiple Real Housewives feuds. Approach calmly, with screenshots or context if possible, privately and without ultimatums. The friend may initially deny it (cognitive dissonance), but research from the Gottman Institute shows truth-telling between friends strengthens long-term bonds.
