What should I do if my roommate is always bringing their significant?
I have gone through this myself. I first talked to my roommate nicely and said I don't mind at all with you having your girlfriend over here all the time she doesn't bother me or anything like that and is always nice buther watching TV using hair dryer taking showers and anything else that includes electric and water is costing more and I don't see how I have to pay more for your girlfriend. If I had my girlfriend over here all the time I wouldn't expect you to pay for her. He said he agreed but asked how can we tell how much she uses? I said easy enough. I went and got a couple of receipts from both the electric and water bills and showed him how much we were basically paying at the time it was just us using both and then a couple of both after she been coming over all the time. One was 22 dollars higher on both and the other was 9 dollars higher so therefore letting him know that he will pay the extra 31 dollars a month. Now if he hadn't agreed with that then I would have said if she's going to come over everyday or every other day then put her name on lease and she can pay it or she's not going to hangout here all day when your working using up the electric and taking showers or whatever to make the bills higher. It didn't come to that because 31 dollars extra a month wasn't worth having friction between us and he still got to have his girlfriend over whenever.
