I'm going to tell my roommate she sucks and made me suffer a lot
What did she do that caused you to suffer?
Well many reasons, she's a party girl and she stole my ex boyfriend
I'm sorry your roommate is not a good person, and you have the right to tell her that her actions are wrong. But you shouldn't escalate it and call her bad names, it will only give out more drama and she might do more wrong things to you.
I feel satisfied after talking to her.
Calling her names won't help if you are stuck in a situation where you have to live with her. Maybe the best thing you could do is find a new place to live or ask her to move out.
