The Miley Cyrus and Liam Hemsworth split has boiled down to just a few reasons that the two couldn't make it work. It appears the majority of the blame falls to Miley, as explained on Hollywood Life on March, 17, 2013.
Miley is a party girl and Liam couldn't tame her, which is the first reason listed for their split. This is something that folks who follow this couple were already aware of for quite some time. Miley's partying was also done in full view of the media, almost like it was an attention grabber for her.
The next reason given is Miley tendency to share too much information on social networks, again this is something that most people were aware of as many of the media stories reflected that noting is sacred with Cyrus. With Liam being more of a private person than Miley, there was bound to be some friction due to Miley telling-all with tweets.
The couple played too many games, which is the last reason given for their relationship demise. Again, Miley seems to be the biggest culprit out of the two. Taking off her engagement ring was a ploy by Miley so Liam would see this in the media and garnish her with more attention. This seemed to have backfired as Miley ended up taking that ring off for good. She got the attention in the media, but the one person she was desperate to get attention from has left her.
