And how you held me in your arms that September night.. Sometimes you learn a lesson too late and at that point you need to apologize because you were careless.." View this post on Instagram Instagram PostThe reason for the breakup varies, but according to a source who spoke in an exclusive interview with Us Magazine back then, the feelings were a bit one sided for the couple:"He liked her more than she liked him. He went everywhere he could to see her, but she didn’t travel much to see him. They decided they were better as friends"The pair had an ambicable split, with the two remaining friends throughout the years, ultimately leading to the actor's recent appearence on the singer's Eras Tour concert.
