<human>: Condense the text into a few key points

Six months ago I moved into a flat with 3 others - a couple I didn't really know well and a friend. The couple have been the worst people to live with and made my friend so uncomfortable she moved out about 3 months ago. A friend of the couple moved in and I decided to battle it out. But the guy out of the couple has been such a dick and his gf who never leaves their room only makes an appearance to back him up. I'm talking him raging out when ever the slightest issue has been brought up, him and the new guy smoking weed most nights, completely denying any attempt I made of getting along and making the flat livable and a million other things so now I'm just sick of it. So I put my room up online and (admittedly txt because they hadn't been home) told them that I was moving out. I found someone great to move in and so I go to them to ask when they want to meet him and see if they would like him to move in and they tell me that they don't want someone they don't know moving in (which i do understand but they can do reference checks its what happens in the real world) and they "have already gone over my head" to the landlord and told him that, and they're trying to tell me that as my name is on the lease I can either move out or stay, but either way I'm stuck with this flat and have to pay rent. I completely lost it and have been thinking of ways to make their lives hell since but really I just want nothing more to do with this flat and the infuriating people in it. If anyone has any ideas on how to get me out of this it would be very much appreciated.
<bot>: My roommates have made our place unlivable and now when I try to move out they say as my name is on the lease I can't get out of it.
