Bachelorette. Why did Ashley need closure? For what? If she only wanted Bentley why go on?

Ashley is just a regular girl who makes normal mistakes. Closure is something we've all been taught helps heal a breakup. Bentley was the bad boy as he was portrayed to us but to her he was her knight in shining armor, that takes some healing whether you are on a reality show or just a girl dumped in real life.
