Despite initially maintaining a loving marriage with Kay, he never informs her, feeling regretful and guilty over his past marriage. In the books, Apollonia is never thought about after her death by Michael, only in the movie "The Godfather iii", does Michael have a flashback about her.
He then flees to Sicily, where he falls in love with Simonetta Stefanelli's Apollonia. Tragically, she's later killed in a car bomb planted by Michael's bodyguard Fabrizio (Angelo Infanti), who betrayed him to his enemies. While Michael gets revenge on those who ordered the hit, Fabrizio is never seen again.
lisbethblom said: Al Pacino in 1990: “Michael loved Kay when he met her and he loved her throughout his life and he loves her to this day. He not only loves her but he also admires her.”
Michael has become a true Corleone (embracing both Italian culture and mob affiliation), and his marriage to Apollonia signifies Michael's official acceptance of this change and what it means for his future. When Michael marries Apollonia, he is wedding himself not just to her, but to Sicily and his father's values.
Michael's pursuit of Kay was partly motivated by the fact that she was free-spirited, she was the humanity in Michael in which he lacked. Michael was desperate to have a white-Americanized life Ironically, Michael himself would be used in the same way, when he married Apollonia Vitelli.
Despite initially maintaining a loving marriage with Kay, he never informs her, feeling regretful and guilty over his past marriage. In the books, Apollonia is never thought about after her death by Michael, only in the movie "The Godfather iii", does Michael have a flashback about her.
By The Godfather Part II, Kay has decided that Michael is a cold, distant, inattentive husband and father, but only after an attempt is made on his life in the family home does she resolve to rebel against him. At first, Kay's rebellion is silent and private: she aborts the child she is carrying.
They would have been married for almost a year. She would have been pregnant with his child and would have learned how to drive. Sadly once she was killed, Michael was never the same after that.
However, Mario only used the word "love" for Michael twice--that he "loved" Kay and "loved his father". Kay was his dream girl. Al Pacino said that Michael loved Kay from the beginning.
After Michael is notified of Sonny's murder, he and Apollonia prepare to move to Siracusa, but she is killed by a car bomb meant for Michael, proving the other Mafia families know where he is hiding.
Michael could have remarried any time after his divorce from Kay and had more children/a second son. Michael wore his wedding ring for another 10+ years.
The Godfather's Michael Corleone may have loved many things, but his first wife Apollonia wasn't one of them. The pair were wed in Sicily in the mid-stages of the groundbreaking 1972 Francis Ford Coppola film, not long after Michael took refuge there after murdering police captain McCluskey and Virgil Sollozzo.
The third and final film in the Godfather saga, The Godfather: Part III, set in 1979, explains that Hagen had died a few years earlier. His son, Andrew, is ordained to the priesthood, and is assigned to the Vatican on Michael's recommendation. While talking with Andrew, Michael remembers Hagen fondly as a great lawyer.
Enraged, Sonny speeds towards Connie's apartment in Hell's Kitchen ahead of his bodyguards. At the Long Beach Causeway toll plaza, Barzini's men trap Sonny and shoot him to death. During a meeting with the other crime family dons to establish peace, Vito realizes that Barzini masterminded Sonny's murder.
During the meeting, Sonny, the family underboss, expresses interest in the deal, but Vito refuses the offer as he finds narcotics too much of a "dirty business". Barzini then approves Sollozzo's plan to have Vito murdered in the hopes that Sonny, as his father's successor, will accept the deal.
Ultimately, Tessio betrays Michael by helping arrange his assassination at a peace summit with Barzini and Philip Tattaglia. The summit will be held in Tessio's fiefdom in Brooklyn, where Michael will presumably be safe. In return, Tessio was to inherit the Corleone family upon Michael's death.
Humiliated, Rizzi seeks revenge by secretly making a deal with the Corleones' chief rival, Emilio Barzini, to murder Sonny. Rizzi sets the plan in motion by having his mistress call his house, provoking a pregnant Connie into an argument in which he whips her with his belt.
An interesting side note is that there is no indication in the novel or the first and second movies that Michael or anyone ever tells Kay that Michael had been married in Sicily let alone how his first wife died.
"We trusted each other." And though they never dated, "I had a little mini crush one time," she admits. "He was performing 'Computer Blue' and he was oily and shirtless and for a moment I was like, 'He's really sexy,' but then I got myself together. We had great chemistry. But our romance was only onscreen."
His place of birth is listed as Hell's Kitchen, New York. And even though his death comes in the third installment (which was released in 1990), the closing events take place in 1997. This means Michael is 77 years old at the time of his death.
Kay had no business asking Michael about Carlo's death. We assume Kay was unaware of Carlo having set up Sonny to be killed, so she was unaware of the need to exact vengeance on Carlo regardless of how Connie felt.
He is also mentioned many times throughout the film; the dialogue makes it clear that Michael is tormented with guilt over ordering his brother's death, and that it has alienated him from his ex-wife, Kay (Diane Keaton), and his son, Anthony (Franc D'Ambrosio), both of whom know the truth about Fredo's death.
He also confessed to her he slept with another woman in Sicily! 👀 Kay was visibly hurt, but let it go. At least he was somewhat honest with her, omitting the fact he got married but Kay told Michael she was never with anyone else during his absence and asked if he was with any other woman.
