The trouble for GBC is that the timing is all wrong. Even if Allison is in the deep depressions, going to bed at 5pm and not coping with 3 young girls, she never attempted self harm.
At the time of her death, she clearly had it together. Youngest daughter is now at school leaving Allison free to work 4 days in the business, run the ballet school etc, etc. evidence has been provided even by OW and Gerard that she was fine, no problems. That very day Thursday she was full of plans. Plans for the future of the business with the consultant she met with that day, plans for the conference the next day, plans to drop off dresses to Kerry Ann, plans for a sleepover the next night etc.
She was happy that GBC came to counselling and had hopes for saving her marriage. She was crossing off the list of questions she had in her diary as they had their 15 min sessions.
There was no reason to kill herself whatsoever.
