Over a misunderstanding conflict occured. He didn't get his way his demeanor changed. Willing to bad mouth your character. make you out to be the bad guy since his life was in shambles. Sad how the respect went out the window from close to distant. The ties were cut family or not you don't try to expose a person because things aren't going your way.
Another scapegoat instead of owning up. More lies more betrayal and shady scandals going on. Better to walk away than be involved. Its heart breaking they say never again but its not the first or last time.
Neglecting responsibility making this appear worthless a lost cause. The value was gone meaningless not holding any value used it up then away with it onto the next.
Another reason to not get involved or care no remorse or sympathy.
