Dear Juliet,
I know about a partner who doesn't like to talk about deep or complicated things--and the more personal, the more he resisted. He didn't suffer from two cancers, but his leukemia invaded the nervous system, creating two different sets of deastating symptoms.
I can imagine how overwhelmed and sad (and maybe angry) you feel. Know that your feelings are real and valid, and a sign that you are normal.
It is often tricky to find places to express and deal with your feelings. The CVH forums are one such place. Do feel safe and cared for here!
I also hope you will find some (however) small space for beauty or rest--maybe just a tiny candle.
With care,
Nouce
