I don't want my roommates baby mama to live with us
Why don't you want her to live with you?
She plays loud music and it bothers me. I'm annoyed by her anyway since she's such a slut
I understand how frustrating it is to have someone you don't like live with you. You should discuss this with your roommate and come to an agreement.
I just want her to move out.
You do have a say. It also seems a bit unfair that she might stay there and not even pay rent. It might be best to look for a new roommate.
