I watched it. It might not be your cup of tea as it was all a bit emotional and sad. Didn’t see any evidence of the husband/dad being a wife abuser though.
It was in her personal diaries published by her biographer after death
Alison Hargreaves climbed Everest unsupported & died on K2 a few months later, had 2 very young children Tom & Kate with her partner Jim Ballard, they had reported financial difficulties.
According to books I've read she was trying to get famous & wealthy enough through her climbing (attempting 3 8000m peaks in one season without support or 02) that she could afford to leave her husband & take the children with her.
A very complex arrangement considering she couldn't then care for the children the 3-4 months while away on expeditions.
She talked of being torn between wanting the children & wanting K2 (doesn't ever mention wanting her husband much though).
I'm still watching now, it is very sad so far.
