Ugh i hate reading this because i had to deal with something really similar to this a few years ago. My roommate was my best friend at the time of 3 years. I had a new boyfriend who she did not like since we were always together and she didnt like him. He basically just thought that she was being a bitch.

Here's how it went for me: my best friend gave me the ultimatum. She said i was different (read: worse), that he was horrible for me and that she didn't want to see him ever again. i was mad at her for making me feel like that so i decided to be with by boyfriend instead and we parted ways. ...forever. It's been 3 more years and we've never spoken a word to each other, at times im a bit sad but then i cant help but think about how someone could do that to you. I would never say that to her.

My boyfriend was all aboard the "yeah fuck her, she was awful to you" train, smug and happy he had won. Which i ended up hating because i spent a LOT of time crying about losing a best friend who was so close to me, it was really painful because she refused to even be associated with me (i had to meet her boyfriend to give back some stuff), i wanted support but he was just happy to "win" me.

Well a year later we broke up and we don't talk to each other anymore either. Part of me is still sad we arent friends anymore but only for a few moments because what would she have been like had i stayed friends? I reached out to a few uni friend who were mutual and found out to my surprise she's cut herself out of their lives too. Off the radar totally, seems like it was inevitable, people like that dont stick around for long. As per my ex, he was an asshole and idiot the whole way through who couldn't see how it was affecting me, i dumped his selfish ass.

Moral: Don't mourn the loss of selfish people in your life, they'll only bring you down. Im glad they aren't around anymore, im glad those confrontations happened so i could see who they really were.
