You made Mattheo mad bcs of your bratty and stubborn attitude. You were ignoring him just bcs you felt like it and he couldnt take it anymore, so he decided to give you the silent treatment. But how we all know Mattheo hes not gonna break it. He just completely ignores you. Even if you hug him he flinches or pretending like you are not here. Not even a kiss cuz he shoves you off.
