<prompt> Human: Me and my roomate moved in together about 6 months ago and since day one his gf basically lived with us. She finally got out of her lease and officially moved in to our house. My roommate does not think she should have to pay rent but should pay utilities. His grounds for this as that he and I still split the same space so nothing should change. I feel that since she has lived there 6 months completely free she should pay rent now that she is able to. Our rent is 1100month and im only asking she pay 200 rent am I being unreasonable?edit: we live in a big house, he lives upstairs and i live downstairs both have our own living area and bedroombath share kitchen  <response>: Wow. Im surprised you let it go on for this long. She should pay her share of rent, but at this point, Id just be looking for a new place to live. Someone as inconsiderate as your roommate is unlikely to be reasonable.
