I think i might have gone too far?

Well, me and my friend through msn got into a game who could make each other mad the fastest(i kn its stupid|) and weill i did not wanna lose, so i told her i would reveal her secret and she said she didn't care, and so i told a close friend of ours, and she was like all mad afterwards although she said she wasn't. and i said ill talk to you later and she said she doesnt want to talk to me ever again. What did i do? someone help me pls. i dont want to lose my friend. :(
