Is OTHER wrong in the post ? POST : John my friend and I are on the lease to a house with two others who are not. A housemate moved out and john said he knew someone who wanted the room. I was away the weekend john set up the interview process and i didnt meet him until he moved in. Upon moving in, john and the new guy brad let me know that brads sister would be hanging around for about 3 weeks till she went to another state for uni. Ok i thought, 3 weeks isnt so bad. After 2 weeks i asked again how long i would have to endure this woman. John then proceeds to tell me that she could be here for 3 weeks to 6 months. Now im a little angry. As she has been exceeding the guest situation in my opinion. As she invites her other van living friend over almost daily as they both dont work. She also had a dinner party at our place inviting her friends which are the brothers friends so cant really complain to much on that. She would bring girls back to sleep with on our couch and in her brothers room. Most of the time this happened during the day when we were at work and some weekends. She also never contributed financially. But did do us the courtesy of cleaning the house once. 

I said i didnt like how she was using the place to her brother. Stating she doesnt pay rent and in my eyes is only a guest here. He said he would talk to her and she was confused why i felt the way i did. In that time we lost another roommate and a room was available. I asked ger if she wanted it, to which she replied "no, she couldnt live with her brother". I offered it to her on a few occasions but "no" was the answer. But things got better that week as i didnt see her. Then she went for a road trip for 3 weeks and i thought my problem solved. 

Upon her arrival back i arrive home and see her parked in the backyard. Her brother comes to me and asks if she can live in the backyard and pay rent and utilities. I say no as i offered her the room on multiple occasions and i didn't want more people in the house. He wasnt to happy about that but said ok. Then i started finding her in the house during the day when i finished work early. When i asked her what she was doing i assumed she made a lie up about meeting her brother who was nowhere around and wouldnt return home for another 4hrs. She would also leave straight after i found her on those occasions. This made me think she was doing this behind my back. I also wasnt sure weather the brother or john were in on it. I went to john and said i think we should kick ben out. As i wanted an end to this situation as i couldnt trust them. I am currently breaking my bond. 

AITA for wanting to kick out the roomate, whose sister uses our house and doesnt live there but the van on the street and pays no rent
