Who Should I Believe?(Sorry if it's really long)?

[deafeningmice981]

Well This girl, Lillie, and a random dry account(most likely her or her friend) message me on Insta telling me how my boyfriend has been cheating on me and how I should leave him and etc. Me and bf have been dating for 11 months and have been really close, I would explain to u how our relationship is close to "perfect" but obviously people would not understand because you haven't seen what I've seen, or heard what I've heard, or actually been with my bf so you would assume he's cheating as well but all I could say is that we are basically in love. So this girl Lillie, I've heard about before, she has a really big crush(almost obsessive) on my Bestfriends bf, well right away I call my bfs cousin and tell her what Lillie said as I cried to her she explained to me this girl has been harassing them all day and threatened to lie to me and my Bestfriend that our boyfriends has been cheating because my Bestfriends bf and my bf told her off for not leaving my Bestfriends bf alone. At first I was a bit skeptical but my bfs mom later called me and assured me that it's not true, but later Lillie sent me pictures of messages supposedly from my bf with her friend, it was pretty believable to be honest but anyone could fake messages right? But What if his cousin was just having his back on cheating or his mom didn't really kno he was and Lillie was right? My bf and Lillie were friends before this drama so what if she knew things I didn't? They both showed equally good proof so idk wat todo
