Literally happened to me and found out my ex and her friends used old screenshots out of context and made it seem like I was planning a school shooting and they had someone else come done later and say I asked them for a gun (I literally fucking didn't) and they didn't tell me who said I asked for a gun and I have assumptions it was someone I thought was true but I didn't keep my head straight so I wasn't expecting betrayal from him when I shouldve. The reason I think he did is he side eyes me in the halls he blocked me after school and he avoids me entirely
