*Not sure if this is the right place to post but I really need advice*

Since the day I got engaged I knew my best friend of six years was gonna be my maid of honor. We were going to different colleges and had become accustomed to different lifestyles (her heavy partying and me a serious long-term relationship). So clearly a rift was forming as she became judge mental about my choices to become serious with my future fiancé. Despite her constant disapproval and negative comments, she was one of the first people I told when my fiancé proposed and I was so excited to begin planning my wedding with my best friend. When I told her she left me on read and then mustered a shitty “congrats” hours later. She has never asked about my fiancé/wedding in the seven months I’ve been engaged. Like no joke she dodges the subject in every conversation and text! Everytime I brought it up she changes the subject and shows no interest. I’ve even gotten eye rolls. Her lack of reaction is honestly devastating, I’m not sure if it’s just her judging me for my choice to get engaged or that she is jealous. She has clearly become all about herself and only talks about partying at school. I guess I’m just asking for advice on how to deal with this and if anyone has ever gone through a similar situation. 😔😔
