Why Facebook friendships sour
Veiled boasting, gushing romantic posts and incessant updates are some of the most common reasons for unfriending Facebook contacts, according to a survey of users.
About 68% of those surveyed admitted they unfriended someone for boasting on the social networking site.
Almost as many, 61%, said they couldn't bear to hear any more about a Facebook friend's romance and how much they love their partner.
Other common reasons for unfriending include "annoying" posts and "inappropriate photos", while more than a quarter of users said they found a friend's status posts "too personal".
A survey of 820 Facebook members by discount shopping site PromotionalCodes.org.uk found that 11% of Facebook members had deleted a friend because they were jealous of their holidays.
Bad language also made the top 10 list of reasons, while more than half of users said they unfriended a contact because they didn't see them in the real world.
An anonymous participant in the survey said: "Facebook is a great way to stay in touch and share information but some people just don't seem to set any boundaries.
"I've blocked people who have posted really intimate information about their sex lives because I'm really not interested.
"And of course we all know people who endlessly go on about how utterly amazing their partner is and how in love they are. Why they don't just tell their partner this to their face is a mystery."
Another anonymous person said: "I am so sick and tired of people trying to outdo each other.
"Some people's updates just scream, 'Look at me!' It's like they are trying to convince themselves that their lives have meaning.
"The truth is, if their lives were so wonderful they wouldn't bother bragging about it endlessly. The happiest people are the ones with the quiet and understated feeds."
A spokesman for PromotionalCodes.org.uk said: "Most of us use social media these days but it's amazing how varied that use still is.
"Some of us are more than happy to share every detail about our lives while others prefer to stay relatively silent.
"Many of us use Facebook to connect with all kinds of people - lots of whom are mere acquaintances. Then we forget that and use the updates feed to talk to our closest pals.
"Our study shows that sharing too much can turn some people off as it can quite easily be perceived as bragging.
"If you care about growing your contacts list it's important to update regularly and honestly but to remember you are talking to lots of people who aren't necessarily close friends."
