I read a story a few years back about a guy who hears his wife telling her friends about the affairs she has had he was hiding in the basement and his wife didn't know he was home one of the friends see him through the basement window when the get together is breaking up and gives him a look of sorrow.
I remember it was a flash story where finding out what his wife did causes him to have blackouts in the lucid memory after leaving his house a cop asks him if he is okay and he remembers he has his pistol on him which he gives to the cop he ends up homeless with his wife and kids eventually tracking him down.
Any help would be to appreciated.
