Something happened at work - a friend (or so I thought) raised a “concern” about me to our manager instead of just coming to me directly. It wasn’t anything serious, just something she thought I’d said in a meeting that she found “inappropriate.” We’ve known each other for years, so I’m shocked she didn’t just message me or talk it out. It now feels like a betrayal. AIBU to be upset and feel like she threw me under the bus?
