Nocturnal Animals : He committed suicide

He blamed his wife for everything. In the book his wife and daughter died. In reality his wife divorced him and aborted his child so they are both dead to him. In the book he accidentally shoots himself after killing his demons. In reality he committed suicide after he finished his successful novel.

Suicide? In the novel yes. In real life I have no idea where you got that idea. He stood her up to prove that he wasn't weak and wasn't going to take her back just because she liked his novel. And I think it dawned on her at the end that she was the villain of the story. What she did to him and his unborn child was unforgivable.

Tony committed suicide at the end of the novel??? You must be as blind as he was - it was very clearly accidental.
This kind of thing happens all the time with idiotic gun-owners carelessly handling weapons - a ex-marine neighbor of mine shot off part of his penis yesterday holstering his gun.

Read again champion.

Only a few more days of these boards- and still so many to educate. He didn't blame his wife for everything- he blamed himself. He blamed HIS inability to do what was necessary (in the novel to protect his family, in real life to give his wife what she desired). In the novel he dies after exacting revenge, in real life the death is figurative. The old Edward would never have stood ANYONE up, least of all his ex- she realizes this: That Edward ( as she knew and loved him) is dead- and she killed him- that's the look on her face at the end.

thats a good interpretation.
