Context: this was a bit over a year ago but i just found this subreddit. so i had 3 roommates who were my friends in college we were all part of the same sisterhood and are splitting a room in the big city to save money. We all met in college and have known each other for years, our closest friends all know each other. One of my roommates has been dating this guy that we used to hang out with so he was my friend even before they dated. The friend who has been dating him had been sleeping around a lot bringing all kinds of dudes home. We went out a lot basically every day for sure every weekend and let’s just say it happened every time. I get it shes beautiful and all these guys are spoiling her with everything she wanted but she has a bf. Her bf is in a different city for work so he doesn’t have a clue she does tell him that we go out on the weekends and apparently he allows her to dance just nothing further. I talked to my other roommates about it and we agreed it’s messed up what she is doing but they said it’s none of their business. I felt bad for him decided to talk to her about it and she basically told me to mind my business and that they were in an open relationship. Fast forward a few months and we go to a party in the hamptons. Huge mansion with a crap ton of drugs and a bunch of rich kids. This party was different tho cause her bf is back in town and is going to be driving us girls to the party. We get really fucked up i wont deny i did partake in the drugs and basically me and the roommates get messy and her bf ends up taking care of us. Shes gone and ik she is seeing her fling cause the hamptons house was his so she finds a reason to go back and ask her bf to take care of us. We feel a bit better after an hr in which he stayed with us and we decide to chat and to just do drugs no alcohol since thats probably what fucked us up. Me my roommate and him just in a room talking and we talked about all sorts of things. But at some point i said i think its pretty cool that you allow an open relationship and thats when everything spiraled. They were not. After that they got in a big argument but they ended up blaming me. My roomates all said i shouldnt have said anything ans that i am an evil person who tried to ruin their relationship. The bf and gf blames me for trying to sabotage their relationship, she convinced him that i wanted him and this was my plan. We have a lot of close friends from college who have turned on me and dont believe my side of the story. Forgot to add i had to move out as well. Edit: a little confusion on how i told him but he was asking us about helping him pick out a ring for her and asking us if we think shes ready. I was in a K-Hole at this point and my brain just spurted out “oh thats interesting didn’t know you were that serious cause you guys are in an open relationship, i do think these new relationships are so cool but i know nothing about it”. I honestly think i did it out of curiosity but i always had a part of me that i think didn’t believe the open relationship was real which is why i never really got into it with her other than the one time she revealed it.
