I'm so sorry ( its a genuine sorry i mean it ), they sound like they weren't true friends other wise they wouldn't have just left you like that. Nobody should be left like that and they shouldn't have reacted like that it wasn't your fault at all, in no way was any of that your fault. People should treat you like that, and you did what you needed to do and they shouldn't use that against you. And I'm also sorry about your crush, i wish that none of what happened to you happened. And you acted way better than i would have honestly.
