With whom was Gatsby obsessed in Fitzgerald's novel "The Great Gatsby"?

I read it first in high school, but never appreciated it until I was quite a bit older and could understand all that was being addressed.

ImpertinentPony72241, I never read it in high school I did read it when I was in my thirties. I could only read a few pages at a time because it was so dense with intense emotion.
