[LOTR] Why were the elves leaving? Did they not think Sauron could be defeated again? Or did they think humans could handle it? Or did they just not care about Middle Earth anymore?

They knew their time was past and the coming age belonged to man.  They could have stayed but would have continued to fade and decay until nothing remained of them.  If they left they would retain some of their essence and be carried into essentially elf heaven. All things move in a cycle and they were no longer needed and left so the age of men could flourish.
