My house

I know that I do live with my boyfriend, but I did not sign up to live with him and his cousin. His cousin moved into the extra bedroom to cut back on rent, which was a good thing. Until I have been living with them for 4 months. They destroy the house everyday and I have to clean it up. Everybody always tells me not to clean it up and they will. Okay... I have tried that on several occassions and it has not worked yet. I am OCD about having the house clean and everything put in its place. I go to school in the morning and then to work in the afternoon. I usually do not get off till about 10 or 11. When I get home they are drunk and passed out in the middle of the mess they have made in the house. I have to clean it all up and then go do homework. I finally get to go to sleep and wake up in the morning and do it all over again. I wouldn't mind if it was a little cleaning, but it is hours worth of cleaning everyday. I am exhausted and getting very tired of it. But, if I say anything then I am being bossy and a control freak. I am seriously reconsidering living here next year. I am about to burn out and I can not handle those two much longer. I want to have nice things in my house, but I do not want them tearing it up. I have a $300 rug I got for my birthday last year and they have already spilt beer and anything else you can think of on it. There is no way I am going to buy nice furniture for them to ruin.
