Betrayal Emergency Negated by alliance offer

[Contrabassist]

Tamar/Georgia was allied with me. I get the "Emergency vs Tamar" screen because she is about to mess with me personally but has not yet declared war or even denounced me. It's my turn. I decline the emergency and click on Tamar/Georgia. I offer another research alliance, she gladly accepts. I end up not being at war with her, but all my city states are, and I cannot select her cities for trade routes. Her city state was at war with me. Eventually the emergency is declared a success, perhaps because she lost her capital. But she never betrayed me like the initial emergency said she had.
