I'd ask your friend why she thinks her dislike of this other person would create any obligation in you to behave in any specific fashion. This other person cancelled a date with your friend, sure--what's that got to do with you? Does she think you need her permission to date people? Why does she seem to have a problem with you deciding how you'll interact with others on your own? Why does she think she has some control over you?
