You have to give kudos to a Hollywood couple who stayed married for 50 years, despite flaws and difficulties.
Staying married to an alcoholic is insanity. The children would have suffered horribly as did his wife
Then you should read of the long marriage of Dorothy and Robert Mitchum, she married him at a young age, like 16 or 17. She knew damn well he was having affairs, but he always came home to her and she was not going to divorce him.
Mitchum I believe did have an affair with Marilyn Monroe, he once talked about her vagina and something unusual about it. He died at home with Dot and his kids with him.
Anyone married 50 years has flaws and difficulties.
And are both certifiably crazy.
