You don't know so shut up and mind your business...
Jasmine recently found out that a friend of her boyfriend, Oolong, told a bunch of their friends that they didn't like her. Oolong had kinda ghosted a lot of his friends and family for almost a year and just happened to meet Jasmine during that timeframe. This "friend" of his thought/assumed that Jasmine came into Oolong's life and manipulated him into alienating them. She went around spreading rumors and sticking her nose where it didn't belong. Ultimately Jasmine and Oolong are still together and this "friend" isn't in their life much anymore.
What none of them knew was that Oolong just happened to get in a bit of trouble and was arrested. During that year he ghosted everyone he really had to focus on healing himself and was in a dark headspace. Jasmine coming into Oolong's life was pure coincidence but was truly what he needed. Instead of his friends gathering around him and supporting his needs, one "friend" in particular made her own conclusions and blamed Jasmine.
You should never judge anyone because you will never fully know all sides of the story. Love and support your friends or be honest and get lost!
