Reasons Harry Styles And Olivia Wilde Called It Quits 

It's no secret that Olivia Wilde and her ex-boyfriend Harry Styles were never really together. 

The age difference was too much. This might have been the most important reason for their breakup.  

Their busy schedules made it difficult to spend time together. They are both on different coasts.

The two are very different people and there were clashes over what to do for fun on weekends or holidays--they really just didn't share the same interests in life at all!

They have different priorities in life which makes their relationship hard to maintain due to their busy schedules and lifestyle choices. 

Another factor that contributed to their breakup may have been how they were never able to see eye-to-eye when it came to starting a family.
