Is AUTHOR wrong in the post ? POST : So I’m in an organization with tons of people. We have bigs and littles it’s co Ed. Anyways, my roommates and I have the biggest house because it’s off campus so we usually have parties and kick backs here. Anyways, I posted here awhile ago about this same girl. Story is she cheats on her boyfriend, she cheated emotionally and physically on her boyfriend with ME. She then got too fucked up one night with her best friend and they crashed in my bed and because I was in the same room as them she falsely implied I sexually assaulted her friend(there were witnesses who have my back and know I didn’t). 

Fast forward to today one of my roommates has a bday and she’s coming because she’s part of the “family” he’s in since we have four separate families within the .org. I’m totally fine with her coming today even though her boyfriend came to town. However, I kinda want to ask my roommates if next time she’s not allowed in my house especially with her boyfriend. The reasoning I have is because I met him before he was cool, she told me she liked me more than a friend and hinted their relationship was bad then she said she loves her bf and now she’s posting on Instagram, she also accused me of sexual assault yet still asks me to buy her alcohol? 

I don’t want her in my house because of what she did to me, I especially don’t want her boyfriend here because I feel bad for him. I’m not the first guy she’s cheated on him with and in my head why would you bring your boyfriend to the house of the guy you were fucking and also accused of “possibly” assaulting her best friend.

I know she’s a part of my organization and I hate to exclude someone(not really) I don’t want to be a dick tho. Knowing her she would act like I’m excluding her for some other reason. But it’s just I KNOW it will be awkward when I see the boyfriend because I DONT want to act like nothing happened. I somewhat want to be distance from him so he knows something is off. She’s never going to tell him and even tho I’m an asshole for sleeping with her boyfriend I do feel bad because no guy deserves it. I think she’s also dangerous to be around if she’s so scared of being found out she’s cheating she’s willing to potentially ruin someone’s life. 

I’m wondering maybe I can just let her come over sometimes if there’s an event but restrict her form alcohol yet I still would not want her boyfriend over ever again. I just can’t stand them acting lovey dovey knowing that she’s a huge cheater.

Am I an asshole if I make a rule like this? I know at least one of my roommates and his girlfriend would agree with me but my other roommate who has a girlfriend who is friends with her may not.
