Harry: rumour has it that he is still in love with Taylor Swift. As much as you'd like to think it's not true, you still feel a pint of jealousy because he never comes home on time.
Louis: he embarrasses you in a bad way. He thinks you can handle it but on the inside you can't. You try to tell him but he doesn't believe you.
Zayn: the smoking. You don't want him to die but he doesn't want to quit cause it's his stress reliever. During a fight he mentioned that you were the cause of his stress. With that you packed your stuff and left.
Liam: the distance. He couldn't do anything to persuade the management to make you come with on tour, and rumour has it that either one of you was cheating. It broke your heart but you had to let him and your relationship go.
Niall: the drinking. Every night he would drink and he always came home drunk. Not once has he been sober to make love to you or come home for dinner or watch a movie. Not once. You got fed up with it and left one morning, leaving Niall confused.
