 But they could see that they were in love and they were fully supportive of Joe getting married to Marilyn if that's what he wanted. Now we know that the marriage lasted only nine months, I think in 1954, and they broke up and went their separate ways. But apparently they still had a strong attraction to each other because what most people don't know, and I learned this from Emily DiMaggio, who again is the only one of that generation still alive. She's in her 90s now.
