Close friend can’t keep a secret

DEAR HARRIETTE: My friend keeps telling others about my private business, and it’s starting to feel like a real betrayal. I recently started seeing someone new, and because my friend and I are very close, I shared the news with her. I was excited to tell her, and I trusted her to keep it between us. But almost immediately, I started hearing from other friends and even some casual acquaintances asking me about the new guy I’m seeing! It’s frustrating because I’m still getting to know him, and I wanted to keep things quiet until I felt more comfortable and surer about the relationship.
