However, the 2012 star told Parade that he always tries to make relationships work.
"Men always think the grass is going to be greener," he claimed. "They fantasise all the time about someone new, even if they're in a happy relationship. It's something that women don't want to hear, but it's true.
"I don't really obsess over women, but I do obsess over how I relate to them. If something's meant to be, I just want to make sure I'm in a good position to make it work."
