Zac and Vanessa ready to split?

So, the other day I was reading/skimming Perez Hilton's gossip blog and stumbled across this section here which showed a seemingly upset Zac Efron with skateboard and phone in hand. Upon looking for some material to write about today I stumbled across in article in Star magazine online, which is linked in the title. It says that Zac wants to distance himself as much from his HSM (High School Musical) image as possible, which would include breaking up with Vanessa Hudgens because people see the two together they automatically think Troy and Gabriella. 

Also, it seems that Zac has tried to stop the romance before since when they were house hunting Vanessa said they should get a house together and Zac said no. He's also been seen traveling and going to premieres by himself instead of with her, like previously, until she shows up. Without outrightly saying it, Star says that Vanessa is controlling and smothering. What do you think? Should the two split after three years (at 20 and 21 now, so 17 and 18 when they started dating)? Is Vanessa the right girl for a guy who said he'd never get married?
