I don't know what happened here, but I can almost guarantee that the full story hasn't been told by the ex-wife. This is not to say the ex-wife is wrong, but I am 100% sure that aspects of the suicide that she was a direct contributor to are deliberately not mentioned in her little comment there. Rarely is a story so one-sided.
One thing that really pisses me off is this:
"I considered not sharing this out of respect for Rich's parents and sister, but after thinking on the incredibly vitriolic wall of text Rich's Mother sent to me this morning, saying upon many other things, that his blood is on my hands, I need to share it to regain some sense of control over what's taken place in the past 48 hours."
Someone is dead. Some vitriolic wall of text from the mother of a person who just died is normal. You need to share private information just to feel better? That is not justification AT ALL. What the hell did she do to push him to put a bullet into his own skull without saying goodbye to his childen? What WAS on that vitriolic wall of text that she is deliberately not mentioning?
