Although I think Jenny possibly needs counselling to help her stop measuring her self worth by the size of her kitchen and the number of appliances she has
Its her workplace from which she looks after the family - its a symbol, she can no longer do the job which defined her life through no fault of her own. I think she is allowed the odd emotional outburst after losing something she cared deeply about because of more of Brian's fecklessness.
I'm afraid that I don't have much sympathy for JD. She was happy to live her life on Brian's money when things were going well (i.e. never bothered to maintain her own earning power) so she can live her life on Brian's absence-of-money too.
Massively unfair. Jenny is typical of most corporate wives who run hearth and home and a chunk of the business for their "too busy" husbands. The partners of corporate spouses could not achieve what they do without those spouses manning the home front. That was her job, including running the business when Brian was ill.
She could have got a job working for the new Shoot caterers or similar.
Because companies are falling over themselves to employ 70yr old women in physically demanding jobs on zero hours contracts.
This downfall was entirely down to Brian's dishonesty, no Jenny's complacency.
