Okay so my bestfriend just broke off our 5 year friendship over a guy. Here’s what happened, she’s been texting another dude off her Instagram but since her boyfriend has her password to her insta (I had her password too) she had to mute and delete his messages every time they texted, so a few days ago the side dude called her out of nowhere and her boyfriend saw it then when he went to go check it was delete and he questioned her about it, since I had her password too I called her and was like why he called and she was like she didn’t know but started panicking when her boyfriend was trinna see who it was me being me I told her to be like it was one of my friends trinna see where I am, so she tells him this and he still doesn’t believe her even after she screenshoted us on FaceTime, so she’s eventually he calmed down and everything’s cool. So fast forward I ended up falling asleep on ft with her and she went on my account and texted her bf telling him that it was my friend to make sure he believed her then he said something and she and him were arguing off my account idk what was said Bc she deleted it, so she makes up a fake argument between me and her off my account so I wake up and see the Instagram notifications but when I went to it it was all deleted and it said that I blocked her so I unblocked her and asked her why was she making fake messages off my account then I texted her on iMessage and asked what where these messages about, me being curious to see what happened whole I was sleep I go to her account and see the messages

Then she texted her bf this off my account

Mind you I was sleep while all this happened so I texted the bf and was like I didn’t text him nun of that but he didn’t believe me. He texted me off her account and told me to leave her alone. She ended up blocking me then watched my page off another account I blocked that account then she watched me off her account then got on one of her friends accounts and watched me. Funny thing is the bf is really toxic and I tried to tell her but she doesn’t listen to me so I just stopped talking and was there for her every time he make her cry, Ik she didn’t want to leave him but I hated seeing her unhappy like this. I really don’t know how she can treat me like this when I really treated her like family I would give her the clothes off my back if I had to, then I took the fall for her and told her to say the side dude was my friend when I really never meet him In my life ( she lives in Texas I stay in Louisiana). I want to tell the boyfriend but then again it was a five year friendship and I don’t want to seen petty... what should I do
