Theodore Nott)

You and Theodore have been a couple for a long time

He had an ex-girlfriend named Sarah, who left and then returned to Hogwarts

You loved to eat so much that your cheeks grew and you gained weight, Theodore noticed it and told you
Theodore: You're fatter... you should lose weight, you're chubby and guys like pretty girls, like Sarah.

Theodore: I'm telling you because I love you.. okay?
