Nosy Co-worker

Hi all!

I work in a clinic and have been there 4 months now.
One of the nurses I work with has been getting a bit too personal lately.

Basically, I started browsing around for a house. This nurse, I'll call her "nancy" gave me a reccomendation for a realtor. So, we found a house and are in the middle of closing the escrow. We had a couple issues with the loan company and "nancy" decided to call the realtor and complain about how we were treated. Throughout this conversation of nagging on the realtor, nancy found out a tidbit of information about some problems with getting us a loan from the realtor.

THe next day at work, Nancy comes in and starts talking about this problem we had with the loan (that my husband and I weren't even aware of!)

I got upset and pulled Nancy aside just the two of us and asked her if she had any questions, to consult me, not my realtor. (I reamed my realtor later)

Long story short, she got very upset that I was angry she had called the realtor about MY problem. Now she won't talk to me at work and is giving me the silent treatment.

Is there any ideas on how to handle this? My supervisor is already aware and thinks I should just leave her alone until she gets over her tizzy fit.
