Gryffindor - Protective, obvious (wants everyone to know that you're with them), treasures the small moments, not afraid to get hurt

Ravenclaw - Knows every little thing about you, gives small romantic gifts a lot, will charm you with their geekiness, always doing little romantic gestures (written poem, learning a new spell for you, etc.)

Hufflepuff - Cuddly, always thinks you're beautiful and/or adorable, loves to surprise you with hugs or kisses, loves just talking to you

Slytherin - Also protective, clingy (drapes arms around shoulder waist, etc.), loves pda, hopelessly romantic
