The "Haylor" duo is over and done given only a quick two months of dating. Fans can't blame Harry Styles for not listening to their advices to steer clear of "serial dater", Taylor Swift. With the romance over and done, it looks as if Harry Styles has finally come out and say it. Harry horribly regrets the decision of dating Taylor Swift.

Taylor Swift is known for many things of which include being a Grammy winner at the age of 20 and having numerous Billboard hits. Of course, Swift is also known for her reputation being a "serial dater." It doesn't surprise fans the least bit to see Swift with one guy then a different one by the next few months. The only boyfriend that shocked a lot of "Swifties" was Swift's decision to date One Direction's Harry Styles.

All thanks to Styles, Swift has once again taken inspiration from their break-up. As for Styles, the British singer could have avoided all the drama if he had only taken the time to listen to his "Directioners. It took a while for Harry to realize his mistake of which he had gladly opened up to a friend.

"Harry might have taken Taylor's swipes with an air of grace, but he now wishes he never ever dated her. I mean, the fact she's aiming a jab at him in the 22 video has got Harry wondering what's coming next! He just doesn't know what to expect," stated a source close to the One Direction singer.

"It wasn't the most amicable of splits, but Harry said all along that he wanted to take things slow and easy with Taylor. There was certainly no commitment made, despite Taylor's protestations and the fact that they were so busy with their careers and lived in different countries meant that it could never have really got that serious," continued the source.

Well, it appeared to be all serious for Taylor Swift because things went entirely out of hand. After the split, Taylor Swift became the scariest ex-girlfriend for Styles.

"What for Harry was 'a bit of fun' at the time has slowly turned into a personal nightmare. But he won't stoop to Taylor's level, he's just going to continue to be the more grown-up person and get on with his life. Perhaps something Taylor should consider too," stated the source.

Indeed, Swift should consider "growing up" and start acting her age when it comes to dating.
