Email from Sandra:
Pages of how terrible her marriage is, and anecdotes from long ago that have been told to me many times.
My reply: It sounds like there's a lot going on at home and you're not happy at all.
I'm sorry.
I'm not going to offer solutions, because that's not helpful.
I am very much looking forward to [planned event in a few weeks]
Email reply from Sandra (paraphrased)
Sorry to have bothered you. I thought you might understand based on your own experiences. I wasn't asking for solutions or advice, just unwinding.
I won't bother you again.
Other info: She has been telling me about her marriage for many years, but won't leave. I am also concerned that she is losing some of her mental capacity (she is over 80). I have set some boundaries of my own due to increasing demands made upon me - I have reduced contact as she increasingly relied on me.
Maybe it's too complex to get to the bottom of here.
