Yes, I agree! The age difference most likely turned out to be a problem later in their life. Moreover, if you put together two highly traumatized people...problems will arise . Not sure how they made it to stay together for so long! It seemed like he found his real happiness later in life. I also feel really weird about his relationship with his kids. I know Jerry loved them very much and it was obvious . Not sure what happened..His kids, however, do not seem to be "perfect" either.
I think they stayed together for so long because Patti simply decided she was going to stick it out - whether for the sake of the kids, for her own sake, hoping Jerry would one day "grow up", because she did not believe in divorce, I don't know. And then when the public embarassment got too big, she had to act. But they had their separations over the years. Also, Jerry kept coming back to her. In her book, she said she believed that he did so because she offered a stability that he wanted and needed deep down. By this time, Patti had her own health issues - physical and mental - and Jerry could not cope with that. By the time she filed for legal separation, Jerry had not been living in the house with her for about a year. I'm glad for him that he found happiness with his 2nd wife and I hope he treated her better than he treated Patti. I think it was also wise to just have one child in the 2nd marriage.
