A bad breakup: Nothing can be as emotionally tumultuous for a young heart.

Except maybe finding out via your Facebook newsfeed that your college ex is dating someone from your fraternity.

That was the defining moment that eventually led Brolin Walters, 24, to ultimately break up with something else: Facebook.

"I didn't want to see what was going on with them," said Walters. "So I deactivated my account."

With a website that boasts 901 million active users and is launching an IPO on Friday, it seems unlikely that once you get on Facebook, you'd ever leave. But deactivating from the social networking site is not that unusual. Close to half of Americans think Facebook is a passing fad, according to the results of a new Associated Press-CNBC poll.

More and more people are stepping away from the technological realm and de-teching. There are even sites where they can pledge to delete their Facebook accounts. And tech writer Paul Miller from The Verge decided to leave the Internet for a year to reassess his relationship with it.

We asked whether any of you had left Facebook, and the responses urged in. From privacy issues to a need for more face time, the reasons for choosing to live without Facebook ran deep.

Maintaining a professional image

Although Walters, now a consultant, initially left Facebook for social reasons, he says he was also thinking about his career.

"You don't want a future employer to find something that they would deem questionable," he said.

Job prospects and personal privacy compelled high school student Alexander Clark, 18, to deactivate his Facebook account as well. Ever since he can remember, Clark has wanted to join the Air Force. Now, as he comes closer to making that dream a reality, he says he wants to maintain a professional image.

"There are things on Facebook that I don't want my employer to see, and what I was told was 'what's on Facebook stays on Facebook.' "

Despite leaving the site for privacy reasons, Clark considers Facebook to be a pioneering company.

"I would totally buy their IPOs if I had the money, but I'm just not [as] into Facebook as I used to be, and I think it is from the life decisions I have made," he said.

Focusing on "real" communication

Putting in the effort to make a phone call: That's what Shiela O'Dea does now after deleting her Facebook account.

O'Dea's move off Facebook was gradual and started when she found the site went from being fun to being habitual. "I was literally on it all the time," she said. "When I first logged off for good, I would think about getting back on. But the more I stayed away from it, the more I realized I didn't need it."

O'Dea says after deactivating from the site, she makes a greater effort to socially engage with others. "It's funny, it's called a social networking site, but we are sort of disconnecting," she said. "It is mass communicating, but we are losing something -- we are losing our interpersonal skills."

Chris Andrus says he started feeling the content on Facebook became impersonal and irrelevant to his life. So he and his wife deactivated their accounts after five years on the site. He says their social lives improved after leaving Facebook because now they focus on more in-person connections.

"We feel like we have strengthened relationships with close friends and family that are truly important to us, and not concerned ourselves with the other hundreds of 'friends' that really aren't important," he said.

Shedding an emotional burden

A study from Utah Valley University says there is a direct correlation between the amount of time spent on Facebook and the way people perceive their lives. Users that spent more time on the site reportedly thought their Facebook friends had better lives than themselves.

That definitely rings a bell for Andrea F. (who didn't want her last name used). She says Facebook made her perceive herself differently, and she felt pressured to be a certain way. The 28-year-old deleted her account 10 months ago when she realized how self-conscious Facebook made her feel. She started caring too much about what people she barely even knew thought about her profile and status updates, she explained.

"To make myself feel important, I made up exaggerated posts to garner attention from friends," she remembers. "Does that make sense ... no, but maybe I was not aware that I was unconsciously doing that until I got off [the site]."
