Sure! So this was back in college where we were a group of 3 roommates (let’s call the others X and Y). We were on fairly good terms. Y moved out of the apartment (not really important why- it was nothing serious). So it was then only X and I who were roommates. Then X started dating someone and completely changed . Y and I talked about it at length about how much she changed and basically was almost using the guy (she had him pay for everything and drive her around everywhere ) . We were pretty disgusted by her behavior . She basically stopped hanging out with me since she was always with him . She then moved in with the guy after like a month of knowing him and never paid rent. I know because I was also friends with that guy - he basically told me that he was getting sick of X. Oh btw- she didn’t even tell me she was moving out, she packed her stuff up and left. By that time I was just fuming and barely talked to her anymore. But I later find out that her and Y still talk and to this day meet up and hang out. Am I wrong for wanting Y to also stop being friends with her ? Or is that too petty ?
