The Bachelor: Why Did Ali Leave The Bachelor Show 2010?

Several days ago, there were tons of rumors about Ali saying she would leave the Bachelor show 2010 (season 14) very soon due to some personal reasons. I never thought it will end like that. The analysts have been granted her with good comments saying she is going well on the show but now, all has finished.
Tonight’s Bachelor episode was the last episode for Ali. Her last name is Fedotowsky, I wonder where her last name is from.
What is the reason Ali left early on the season 14 of the Bachelor show 2010 tonight? Why did Ali do it?
Will she return later and win?

Tonight's Bachelor rose ceremony was unique because Ali chose her love of her job/career over her feelings for Jake. It definitely made for a creative ending to last night's episode.
Ali (often misspelled as Allie) had a big decision to make during last night’s show – and what she decided to do at the end of the episode was as devastating for fans as it was for Jake.
Why did exactly Alie leave The Bachelor 2010?

Ali decided to leave the show because of work-related issues. Ali described the whole situation as being torn between the two loves of her life (work and Jake) she does have a nice and secure job at a moment where the economy is pretty bad. Alie ultimately decided that her job as an advertising account manager was more important than Jake and left the Bachelor show 2010 for good.
Of course she's not coming back.
