Out with the Old and in with the...Older??

As The Great Gatsby by F. Scott Fitzgerald progresses, I couldn't help but notice that through all the struggles and hardships going, things seem to be reverting back to how they were at the beginning of the novel in terms of the overall situation.  When Tom says "It was a yellow car (p140)" we can assume that Gatsby was the one who hit Myrtle.  Later, Gatsby reveals to Nick that Daisy was the one driving and that he will take the blame.  While this is admirable and in a way the ultimate sign of his love, in the end it simply means that Gatsby will either have to flee New York or risk imprisonment.  Like before he met up with Daisy at Nick's house, Gatsby will ultimately be out of the picture.  This opinion is strengthened by the fact that Tom and Daisy are becoming closer again.  With Myrtle out of the picture, Tom is again bonding with Daisy.  Nick said "There was an unmistakable air of natural intimacy about the picture (145)" when talking about Tom and Daisy talking after Myrtle's death.  Their relationship might even return to how it was when they were married. They could fall in love again.  Lastly, Nick seems to be losing his attraction toward Jordan.  He won't talk to her after Myrtle's death, and when talking on the phone, one of them hung up on the other, and he doesn't seem to care.  So overall, like before the events of the novel began, Tom and Daisy are living together with no affairs somewhat happily, Nick is single, and Gatsby has little to no hope of reuniting with Daisy.  While the death of Myrtle was certainly tragic, this ending seems to be more convenient than I expected.  On the other hand, Gatsby still has yet to escape his situation as the supposed killer of Myrtle.  Maybe his story will be more tragic.
