hi,
I am a college freshman. I live in the dorms. I have a roommate who has hurt me. At the beginning of the year, we were good friends (in my opinion). We would do things together and talk a lot. Then I don't know what happened but she just stopped liking me/wanting to spend time with me. I don't know how to act around her. Since nothing discrete happened (we haven't fought or anything), I never confronted her. I thought if this girl doesn't want to be my friend, I'm not even going to make the effort to repair the relationship. So far when I have to see her I'm fake nice, but that doesn't feel good because it's fake. I don't want to be mean though because I know that wont feel good either. She's hurt me... and I just don't know how to act around her. How do you guys act around people who have hurt you in the past but you have to continue to see? I don't think I want to confront her because then that will give the impression that I want to be her friend and I want her to start including me in stuff, when at this point I don't because I don't want to be around people who don't want to be around me. I just need a new technique to feel okay about this situation going into next semester. I need a way to deal with this negative energy.
I have been pretty passive and not done anything to assert my power in the relationship - I've just let her hurt me and I've continued to be nice and everything. I kind of want to do something to her (like I brought a TV at the beginning of the year for our room but I dont even watch it but she does so I thought about maybe taking it home...)but I feel like if I do something like that it'll just make me feel worse. Is there a way that I can feel strong and in control in this relationship - and not like a victim who just got hurt by her - without partaking in petty behavior?

You can stop reading here if you want, but if you want to read more details about my relationship with my roommate, like different things that she's done to me and stuff you can read below (totally optional):

She stopped inviting me to do things with her. At first we made friends with people on our floor together... then one weekend I went home and she became better friends with the people on the floor and just all together stopped inviting me when she was going to hang out with them so I was alone (since I have made other friends). At the beginning of the year I was super nice and introduced her to my friends from high school and always invited her out and stuff so I don't know why she didn't repay the favor. whenever I'm going to hang with people on the floor I invite her. Also whenever I'm going to the cafeteria or anything I would offer to get her stuff (i dont do this anymore). At the beginning of the year, we would like each other's stuff on social media... like she would like all my stuff and she would post pictures of me... everyone on our floor said they thought we'd be best friends! i thought we would be too... but yeah now she never likes any of my stuff on social media. after she stopped liking my stuff, i had continued to like her stuff just to be nice and to hopefully get her to like me more, and she still didnt like my stuff so i stopped liking hers. i had to unfollow her on all social media because it was just negative energy every time she popped up on my feed. I was also really nice because her boyfriend has come in town a few times and I went out of my way to sleep in other people's rooms so she could be alone in the room with him. and when we talked about it i didnt just say "yeah, fine, I'll sleep somewhere else tonight" i was super nice about it - because she was saying how she felt bad kicking me out and I told her that I didn't mind at all and that I was happy to do it.

i just cant tell with her! she's a nice girl ... like she's never said anything outwardly mean to me, but her actions have just been really hurtful.
