Why did my mother react this way?

I live overseas with my husband (I am 34) and am currently visiting my parents here in the US. As an only child my parents really want us to move to the US, and my husband is currently looking for a job. I also want to move back to the US not only to be closer to family and friends but to work...due to visa restrictions I am unable to work in the country we are currently living in. Anyway my mother has been asking and asking about what jobs my husband is applying for. I told her what I knew, but as I don't know the specific job titles I thought I would be best to ask him to email her what jobs he's applying for (specific job titles, etc). When I told my mom this she got so upset that she started yelling and crying! Telling me this was totally out of line, that I did this to be mean and spiteful and that she would take this betrayal to her grave. I honestly do not know what to make of this, and neither does my father, especially as I thought she would like an email from my husband with this information...they have, or had, a very good relationship. Anyway she refused to talk to me for a couple of hours, then repeated that I was mean and spiteful, and just now decided to tell me I have broken her trust and she can no longer have any sort of relationship with my husband or with me. She also informed me that we probably will never get over this, and she no longer wants to know anything about our personal life. I'm really not sure what's going on here. Was I out of line? My mother is saying things like she cannot treat me like a daughter now, that I did this to hurt her, and that she now can have no relationship with my husband. Did I do anything wrong? I am honestly confused and worried!
