I'm going to cause my roommate to get kicked out
Why do you want to get him kicked out?
The house is dirty, he always forgets to pay the rent and he's really rude
He sounds like a terrible roommate. You should talk to him about it before trying to get him kicked out, but if you can't resolve it, it seems reasonable to do so.
I can't just talk to him when I want to. I want to get him kicked out and live with a better roommate.
I get why you are upset, and he does sound like a bad roommate. I hope you get him to leave and are able to find a better roommate.
