Thank you for your time, and I do hope to get back with you. 

Cheating: The only times I can think of would be with Alex and Richie, and with Maxx. The thing with Maxx is something the fronter at that time is currently working through, as they do very much regret it. Very few of us feel attraction at all, so this is something I cannot speak on. 

The event with Alex and Richie is a very complicated story. We were best friends, but at one point i made the mistake of saying i had a crush on Richie to Alex. Directly after, Alex had stated that he had a crush on me, while dating Richie, and he wanted us to be in a polyamorous relationship. The fronter at the time was okay with this, the cofront wasn't. They decided this would be something to think on first, and told Alex this. However, Alex definitely took this a lot more extreme. He had started to try to come on to them, kissing them and more. They displayed signs of fear, telling him they weren't ready for that and wanted Richie's consent at least. Alex did not seem to care. When they tried to put up more of a firm no, Alex would whine and plead and try to manipulate them into being okay with it. It got more and more intense, with threats of suicide and other things thrown into the mix, until they caved in. Within just a kiss the guilt had already hit them, but Alex wanted more. I'm sure you can guess what the "more" is, and unless you ask I won't go into detail. This entire time, however, the two fronters from before made sure they were always active so nobody knew (except me, as i got the memories as it happened). Everything that happened had the body and fronter(s) shaking and close to tears. Eventually, after some period of about a month or two, they broke down and told Richie, stating multiple times that they didn't want to. However, Richie immediately blamed them. Many things were said from Richie that I am unsure to blame him for, such as telling us to kill ourself and similar things. Eventually, Richie stopped responding. Richie's sister sent texts over instagram, saying similar things but harsher. The fronters went into a full breakdown. The phone was turned off, and I was summoned to withhold the body for a while until someone else could front. I disposed of evidence of what happened, simply noting to the next fronter to not contact them or ask about what happened. This was kept until the two fronters would return and we could give a very watered down story of what happened to the alters that couldnt have the full memories. As you may guess, Cole and Mirali were ones that had the watered down versions. 

During the start of this, we had a partner named Xavier. He sexually assaulted us in front of both Alex and Richie, though they claim it didn't happen. 

If I'm being honest, I'm unsure what "competitive EDs" means. If you can reword that or give an example (even if it wasn't something done by us) I can try to help you more with that. 

Keeping friends from making new ones: The only things I can gather from recent years is asking people to unfollow/block r*p*sts. The situation with your friend was a misunderstanding, and Cole apologizes for what he said, as it was meant in a joking manner. We only knew her before in elementary, and she has very well changed since. The only other times this topic is relevant is in 6th-7th grade in which our partner at the time made us think being controlling is okay, we have since apologized to the people affected. Us being in 7th grade was a very long time ago, we are in 11th now. We have only gotten therapy recently, and have been working towards fixing what we wrongly believed was okay.
