News of Glee star Cory Monteith's death by cocaine and alcohol overdose on July 13, 2013 stunned his fans across the world. The heartthrob actor was only 31. He had struggled with drug addiction since he was a teenager.
Cory's mother attributed his struggles with drugs at an early age due to the lack of a relationship with his father. In an interview with Good Morning America she said that Cory tried extra hard because he had been "invalidated" by his father.
Cory's father, Joe Monteith, denied this and blamed Cory's mother instead. He said his job in the Canadian military forced him to be away from home for months at a time, but he tried to maintain a relationship with Cory. In fact, he says his ex-wife prevented communication and returned Christmas gifts he sent to his son.
It's hard to determine whose side of the story is correct, but there is no dispute that Cory and his father didn’t have a close relationship. At one point, they went eleven years without seeing each other, until Cory contacted his father about two years before he died, according to Joe's interview in People magazine. It is interesting that it was Cory who re-established contact, not his father.
