Jenny, you must do what you think is right at this point, but I don't see it as revenge. They are clearly taking advantage of the idea that they are expecting you to be so much politer than they. Typical of bullies. When it comes to the utilities and such -- if they are in your name you are going to be responsible for the bills. Do you honestly expect them to suddenly start paying them?

All I am saying is don't let your desire and inclination to be a responsible and fair person allow them to make you more of a victim by using it against you. They are using you to the point you are being chased out of your home; there is no need to make it easier for them. Protect yourself so this nightmare goes away and you can make a clean break and get it all behind you.

I had to move out of one place under similar circumstances -- my housemates always had "friends" over who stole anything that wasn't nailed down. You'd be surprised how quickly a motivated crew can get a place packed up! In this case, my housemates really weren't the issue, so I left rent to the end of the month.

Whatever you decide to do, be happy about it -- you are going to go to a much better situation very soon!
