My roommate always invites herself out with me and is really annoying what should i do?

[Cheyenne]

Okay so me and my roommate get along really well. But whenever i want do something with my friends shes always like "can i come?" Or something. I feel bad saying no because i dont want to be mean but she always does this. But when she goes out with her friend she just leaves. I dont want to lie to her and tell her im doing something that im not because i would most likely post pictures on social media. Also its not like i can just leave my room without her knowing because its a small dorm and we share a room. Please i want her to get her own friends and not to come out with me. Whenever she goes out she hooks up with guys and gets really drunk. And i do not want to be associated by that. What should i do?


Also she copies me..... Like she got the same watch as me, and backpack... And its annoying?


What should i do?

Just tell her that you need your own space. If she has her own friends then why follow you?
Just have a talk with her, maybe she has a reason to do things like so.
Talk nicely, don't pull up a fight.
