My partner has plurality. I don't know that it would fully fit the criteria of DID, because most of the time he's aware of his "aspects". However during traumatic moments in his past he has lost memories and it's thought that these times one of the aspects took over. One time he was suicidal, and one of the aspects surfaced and subsumed the others for a time to protect him from acting on his ideation, and when I talked to that aspect it was VERY different from his normal self. It felt like a completely different person. And it was quite unsettling. I didn't feel unsafe, but it was much more in line with what I would consider a DID switching experience than most of his other experiences.

Perhaps dissociative identity is on a spectrum, and some people have full DID, and others have a lesser form of plurality that they have more control over? His mind works differently to mine, that's for sure. I don't believe he's faking it, I think he's trying to express himself in the way that comes most naturally to him.

Internal Family Systems Therapy has worked wonders with him, more so than any other therapy, because it treats these aspects as natural and normal parts of the psyche. Since starting IFS his depression, anxiety, dissociation and even psychosis has decreased HUGELY to the point of almost disappearing entirely.
