58. He Walked Out
Michael Caine never should have married Patricia Haines. Though he adores his daughter Dominique to this day, as he says, she was, "the wonderful straw that broke an already very weak camel’s back." He couldn't take it, and he just...walked out. He carried on his life as a struggling actor, went off to party with Terrence Stamp and Peter O'Toole, and left his family behind.
When he finally married Shakira in 1973, he knew he didn't want to repeat the same mistakes. And, seeing as they're still together almost 50 years later, I'd say he pulled it off.
