Again from personal and counselling experience, i can confirm that there are no 'rules of behaviour' for suicidal people.
Just because someone constantly threatens suicide does not mean they will never carry it out - that is a popular and untrue misconception.
Just because someone shows no disecerable suicidal behaviour, even after close post-fatality analysis by family and friends, is no indication that an individual is perfectly safe and OK.
To sum up - we are all human, we all act and react individually, so 'rules' simply do not apply in this, or any other case.
This was, and remains a tragedy, and to apply some level of arbitrary judgement based on very basic facts and no personal knowledge is high-handed and pompous, and does the view holder no faviours, even when expressed on here to another group of total strangers,
A woman has died in tragic circumstances, that is very sad.
Anything beyond that - in terms of deciding a level of blame / responsibility based on arbitrary moralising is simply redundant - and leaves a nasty taste.
The moral high ground is looking particularly crowded this morning ...
