I have a very close friend. We lived in the same village for eight years until work caused me to move away, meaning that we see each other only every two or three months (she has disabilities so it's always me who has to travel, and my work is very full-on). When I moved she was heartbroken. We have an hour-long phone call every week.
In the past we have shared a lot, both in terms of experiences and conversation. I am a very open person with no real secrets or interesting skeletons in cupboards, but the friend has told me all kinds of things that she has never told anyone else and that would be very embarrassing for others to hear. For this, and other reasons, and from her very warm comments and reactions to me, I thought that we were equally special to each other.
Somehow, immediately after our conversation yesterday her phone didn't hang up properly or, possibly, she pocked-dialled me. My phone was on silent so the connection from her phone went straight to my answerphone. When I later saw that I had a message from her I naturally listened to it. What I heard was a recording of the friend talking to her husband (also a good friend) about our conversation (no problem with that). However, she also made various derogatory comments about me and about my family, saying, "I would never tell her; it would be too hurtful." She was also very critical of my daughter. None of the points that she made were justified.
So, what do I do now? If I go cold on her with no explanation she will demand one. If I tell her that I heard the things that she said to her husband she will be beyond embarrassed and this will send her husband (who has considerable mental health issues and for whom she is his rock) totally off-kilter, as he relies on her emotional stability, which is generally very sound. My instinct is to simply pretend that this didn't happen, but I'm someone who is always (autistic!) utterly honest and straightforward, so this will be very hard for me.
Am I being unreasonable to ignore this event and carry on as before?
Help!!!!!
