She is rude to my friends

RELATIONSHIPS | DILEMMA

Teddy and I have been dating for three years. She moved into my house six months ago but things haven't been the same, especially when my friends visit. She never wants the boys to come to my house and watch soccer with me. She says they make the house dirty and eat our food. My friends no longer want to hang out with me, especially when I am with her. How can I make her change her attitude towards my friends?
