Slaughterhouse-five #7

The book Slaughterhouse-five, written by Kurt Vonnegut, details the life of Billy Pilgrim. One key feature of the book is the relationships that Billy has with those that are most important in his life. The importance of his father was stressed in the original diagnosis that Billy was going crazy. It was at that point that his mother was able to come to him everyday and, to a certain degree, help him in his struggles of overcoming those relational issues. After this, it seemed that Billy's focus turned to his wife and that this relationship was what kept him intact and whole again as a person. He found meaning in that relationship and was able to hold everything together with his social life, etc. while maintaining this relationship.
I find this build up throughout the majority of the book to be of such importance because in a way, these relationships are not only non-existant in his alternate reality, but the opposite is much different. His relationship with the girl on his zoony planet appears to be purely physical and solely for show of the aliens present. But why does he tell us all of this? I believe that it's because the real relationship that he comes to love and care about it broken by the loss of his wife dying. I see this in the way that he thinks while he is losing his sanity. He chooses to recall his wedding night when he flees his home and goes to New York City. "There had been French doors on the Cape Ann love nest of his honeymoon, still were, always would be."(199). This sentence keys me in on the fact that as he is losing his mind, he focuses in on the past that was good to him. He decides to recall a wonderful time that he spent with his wife (and included in previous parts of the book) into the part where he loses his mind.
