<human>: Can you condense the text into a few key points?

My girlfriend has a high level of expectation of privacy with what I tell my friends/family. We had a few arguments over it but I respect her right to privacy. I told her I answered my friend's question about what her parents do. I mentioned broad field her parents were in. 

I didn't realize it was a taboo topic on her list at the time and we weren't serious then. I felt it was a simple enough question to answer. She says she can no longer trust me after she discovered this. 

To be fair, this isn't the first time I said something she felt was overly personal so it wasn't a make or break situation. I have since done my best to mention very little of her personal life to my friends.
<bot>: I mentioned I once told a friend what her parents do for a living before GF and I were serious. GF says she no longer trusts me with her privacy. Is she having too high of an expectation?
