Input: So, this happened my senior year of high school.

My best friend (we'll call her Lura) started dating this sentient dab of sour cream wearing cowboy boots, we'll call him SC. I was very happy for Lura since this is the first time she's ever dated! SC was friends with my boyfriend (now ex) and seemed pretty harmless at first until he started to show his true colors. He would insult Lura's art and call her intrest in anime stupid. Kinda shitty but whatever.

Then, SC started to become very possessive of Lura. So possessive that he would immediately take her to his car after school (which was weird on its own), not letting her hang out with her friends until her mom picks her up.  He would complain if he saw Lura with me or any of her other friends, saying he was being neglected. He wanted to know *everything* about her. Someone had told her a confidential secret, and SC kept pressing about wanting to know. He then guessed that it was about me, which it wasn't, and thought I was transgender because I was one of the few girls at my school to  wear pants year round. 

Fast forward towards the final few months of our senior year, I had acquired SC's number for some reason and my trust in him had dwindled drastically. I had KIK at the time and his profile popped up on there. My profile was called Altan, the name of one of my characters that is Mongolian. I decided to shoot the piss and contact SC. I acted like I had never met him before to see if I could find out some random things about him. I made up a bs story about living in Mongolia but my dad got a job in the US so we moved there. *He actually bought it.*

We would continue to chat for a few weeks and I had won his trust I guess. I had asked him if he had a girlfriend because I needed "dating advice." SC told me he had a busty chick with a big ass (Lura) but was also fucking this other girl.

*HE THEN SENT ME NUDES OF HIS SIDE CHICK*

This was all the evidence I needed. After reverse image searching the picture to make sure it wasnt some random thot, I took screenshots and planned to show Lura at school after discussing it with another friend of mine.

Redemption Day comes. I reveiled the receipts to Lura and, of course, she was devistated. She broke up with him a couple of days later despite him trying to object about it all. Toxic relationships over and I told SC I was Altan. SC was pissed but I felt like I had done the right thing.

Sitting back and looking at it now, it's been 4 years, I don't know if it was an asshole move of me or not to initiate the breakup. I didn't trust SC with my best friend at all and I could tell his possessive nature was affecting Lura.

I mean, today she is happily engaged and living her best life. SC had a shotgun wedding with some chick that has more testosterone then he will ever have, but I've never seen him since.

TL;DR: Catfished a possessive and cheating piece of shit that was dating my best friend, they broke up.
