I'm going to kick my roommate out just because he's annoying and I do not trust him.
Do you and your roommate typically argue?
Yes, he's a horrible person and I don't know how he got into the house to begin with
You may have your reasons for distrusting your roommate, however, you should not feel entitled to just put him out. If you cannot work out your differences, you both should make a reasonable plan to live separately.
I'm the one who lives in this apartment and we are roommates. I can do whatever I want.
You need to get together and work this out. Just kicking him out is wrong and it needs to be discussed.
