You two are dating for quiete a while now and Dumbledore even put you both in one dorm...

He was quiet formal, possesive, cold and jealous

the dorm only has one bed so you sleep together of course..

Today you also had a huge fight about something stupid

Later that night you came back in and saw mattheo laying on the bed, looking at his phone, he was mad

You were still super annoyed and decide to take the couch for tonight So you lay down on the couch, ignoring him
