I think that there was another ending of this story...

After we left the garage, we went straight back to East Egg. Jordan decided to spend the night with Daisy, and Tom called me a cab. As I arrived home, I saw Gatsby sitting by the door, face ashen white. He had been waiting for me. During our conversation, I learned that Daisy had been the one driving, not Gatsby, as everyone else assumed. He was going to take the fall for Daisy. “I can handle whatever punishment there is, but Daisy…” he paused, trying, I am sure, to think of how to phrase his next statement without sounding insulting. “She shouldn’t be pulled into this. It wasn’t her fault, that woman just ran in front of the car! No way to stop, no time. It all happened so fast…” There was a silence, and in that silence, I felt I understood the man in front of me more than anyone ever had.
We talked a while longer, until the first rays of dawn arose. It was then, we realized, we could no longer deny the urge to fade to sleep. The next day Gatsby told me that Daisy devorces with Tom.

In the evening I went to the house of Daisy and Tom to learn about everything. Jordan was already there. There was a terrible noise, Daisy pack your bags, Tom explained that in love, then confessed to treasons. I offered to Jordan to leave from there.

Since I had a lot of work, I could not contact with Gatsby. And here at the weekend, I once again came to him, where else was Daisy. They were happy, I have not seen such beautiful eyes nor a single person.

And so I myself was glad that I have found a great friend, and he have found a girl which he love...

In my opinion it would be the perfect end to this novel, like a fairy tale :)
