I (22F) was dating Tristan (21m) for about six years. The first few years were great. We did everything together. You know high school lovers, the whole shebang. The last year or so we were together, I found out he got back into drugs and alcohol (a second relapse) and had cheated on me more than a handful of times. To be honest, there was a lot going on. His mom had cameras set up downstairs aiming at the couch I was allowed on. He made me pay for tattoos. He had sex with me while I slept... a lot of things the point is looking back, not a very good guy.

When we broke up, he found out where I was hanging out with some coworkers and got out and caused a scene in which I had to contact his family. I also contacted his best friend, Jack (21m), to keep an eye on him since it was no longer my place, especially if he's gonna threaten to kill himself and me. This got us into further contact, in which we started talking about how he used to laugh about cheating and how he had the best life with someone willing to do anything for him. I began to tell him everything that had happened between us, which included what I listed above, and he started relating some of his past experiences with my ex and how drained he felt trying to fix his mistakes.

Well, after a few days of chat and showing screenshots of some of the harassment from both sides (Jack and Mine) going on about a year into us being broken up. He told me he unfriended him. Completely cut ties with him and his family.

I feel like I should've known that it'd come to something like that, but I feel like I unintentionally intentionally caused him to lose his so-called last line of support. I feel very guilty, but I'm glad the friend is doing better for himself now. I just feel like I feel more guilty about it knowing that my mom just ran into my ex at a festival saying he looked worse for wear and was apologizing to her at the booth he was suppose to be running.

I know he was not the best to me, but I still remember how he used to be, and it makes me feel terrible. Am I the Asshole for basically causing his best friend to cut ties with him, too?
