My 'dad' wants to let this girl move in again. I tried to help her once and she was being a complete slut. She tried to get in the middle of my relationship. It didn't happen. I'm not helping her again. Now she is persay pregnant. I don't believe it. She copies others and when it gets about time to prove it she makes up another lie. I use to be close to her before what she did. Now I'm the bad person because I don't want a 'pregnant' slut where I'm living at. If she wouldn't cheat on every guy she gets with she would have a place to stay. Am I in the wrong in this?
