Later in the show, his and Athena's strained relationship proves to be catastrophic, taking a toll on their two children. Both still want to be together for the children but it is quite obvious that there is very little love left in the relationship. In "Karma's a Bitch", Athena and Michael break up and later get a divorce.

In "Christmas Spirit", Michael tells Bobby that he has been diagnosed with a brain tumor. He also warns Bobby to not tell Athena until the holidays are over.
In "Seize the Day", Michael reveals his diagnosis to Athena, May, and Harry, and he decides to not have surgery on it, as he feels it is too risky. This greatly concerns May, who fears she will lose him after she discovers that he is changing his will.
By the events of "Pinned", Michael informs Bobby that he doesn't think he will live much longer. He tells Bobby that he has gotten see May grow up but worries he will not get to see Harry grow up as well. Bobby promises him he will continue on his legacy with Harry if that were to happen. In a separate conversation, Athena shares with Hen that she believes Michael will not make it much longer either.
However, in "Powerless", Michael undergoes a CT scan and meets a male doctor while trapped in the elevator after the power goes out. Their interaction is positive, but is cut short when Michael receives a call from Bobby that Athena is in the hospital. He then rushes away, leaving the doctor behind.
In "What's Next?", Michael receives the news that his tumor has shrunk by 30% and will no longer be a problem for him. He is excited by the news, and as he is leaving, he runs into the doctor from the previous episode and the two go to dinner together at the conclusion of the episode.
Michael and Athena were married for fourteen years before Michael came out to Athena as gay. She was shocked and felt angry and betrayed by Michael. The couple went to therapy and attempted to maintain their marriage for the sake of their children, but Athena eventually realized that they would have to divorce or she would become too resentful and hateful towards him.
Following their divorce, Michael and Athena remain close friends. Despite a few awkward moments, they work hard to raise their children together and support each other's romantic relationships.
Michael instantly takes a liking to Bobby and encourages Athena to be with him. The two are shown to be good friends throughout the series, often sharing personal struggles and bonding over being father/stepfather to May and Harry and their worry about Athena. Michael does have moments of jealousy with Bobby, especially when Harry runs away from home to Bobby at the fire station, but Bobby reassures Michael and the two reconcile.
In the season 3 episode "Rage", Michael reflects on a traumatic traffic stop and tearfully tells Bobby that he is glad Bobby is the kids’ stepfather, because Bobby loves them like his own children. Bobby is also the first person Michael tells about his tumor.
