u and Theodore were dating. You had an argument last week, that was bigger than your usual small ones about his smoking. So you both agreed to take a break from each other. You guys didn’t break up, just a short break to think about what you want from the other person in this relationship

Today there was a Slytherin house party. Two days after you guys decided on the break. Theo was having fun with his friends then he sees you kissing another guy
