<prompt> Human: I live in a four bedroom apartment that allows one person per bedroom. As each pay our separate rent and then split utilities power and water four ways. Over the past few months, my water and power bills have increased significantly. We now paying over 100 each for power and water when a few months ago it was closer to half that amount. I expected power to increase a little with cold weather, but not to almost double. Anyway, one of my roommates boyfriends has been over almost 247 for the past couple of months. I know that he has his own apartment in the same complex, but it seems as though he is just always here. Ive come to think that he has now moved in here and is taking advantage of our apartment causing our utilities to dramatically increase.Should i talk to my roommate and tell her that this is not okay and ask that he start to pay part of the utilities if this continues? Any advice is appreciated!  <response>: Sounds more like a rrelationship topicIf the boyfriend moved in then yes, make them pay their share of the utilities. If they didnt move in then I would have a serious group talk with the roommate about the bills and how you guys are concerned with the rise
