AITA For having my heart broken?

However, later on, I'm hanging with my closer, and nerdier group of friends. (There's three of them in the group. We'll name them by letter. A, B, C. Friend A is my lifelong childhood friend and also the one whom Rebecca tried to befriend. Friend B is not relevant, but still there. And Friend C is my friend who hung out with me during my middle school years, along with Sam's friend and my ex, Catherine. [Yes, for a total of 5 ex girlfriends].) To specify, I'm hanging out with friends A and B. I learn via Snapchat that friend C is hanging out nearby with Catherine and Sam. (Its not unusual of Friend C to hang out with Catherine, but Sam is new.) I learn that Sam has been flirting with Friend C. Friend C claims he doesn't mind despite the fact I testify to the fact she's an asshole. This is extremely selfish of him considering this is the first time interacting with Sam, and him and I have been friends for years. So I tell Friend C basically the entire story above this comment. He doesn't respond at all and continues to flirt with Sam. I then beg Sam to not take my best friend away from me (over text), as I know Friend C is very easy to manipulate. Sam replies with no remorse claiming "whatever happens happens". I reply she is "pulling a Rebecca" which annoys her greatly. So I tell friends A and B that I want nothing to do with Friend C, as he doesn't do anything for me as a friend, spend any time with me regardless. They've made several attempts at getting our group reunited by completely trying to ignore this whole complex of drama. One night in a fleet of mischief I tease at Sam via text in an immature matter by sending her message "funny this all started with a dance, huh?" To which she replied "actually it began with Rebecca, now leave me alone." I replied "Well you looked to her a role model, didn't you?" I them copied and pasted a conversation she had had with a lonely acquaintance of mine (which I had acquired form a middle man, another one of my friends.) with a two word commentary somewhat along the lines of "quick to bust out the sympathy, weren't you?" She fails to respond, but she's hanging with her very drama-prone friend who requests my phone number so that she can bash on me over the phone. She resorts to asking her sister, Emma, for my number. I tell Emma to give the number to a local 24-hour gym for my own Mischief's sake. She send it, and Sam realizes that Emma, who is supposedly her best friend, actually favors me. This causes her to reach tears along with the sending of the conversation, which allows her to escape her bubble reality that everything goes her way.

Reddit, AITA for the last provocation, or is Sam/Friend C the asshole for ignoring me for the sake of revenge of revenge or a pretty face respectively? And don't worry, I know I'm the asshole in regards to Adaline, I wish I could make it right, or even just confess how I wronged her. Thanks for any input, and feel free to ask any questions.
