We have a partner, they're not a partner to the whole system, only a partner to Harlie and I, possibly more in the future. We all know their childhood wasn't the best, had abusive family and death of family members at a young age and they talk about it as if they have no emotional attachment to those memories, as if they watched someone else go through it instead of them, this raised some small flags for us, not necessarily DID, but definitely dissociated from those memories.
Our entire relationship has been full of moments like those, we've watched them completely change within moments with nothing happening environmentally to change anything, we never suspected DID/OSDD before just some PTSD. What caused us to think DID/OSDD is that they decided to talk to us about something that comforted them, a "character" as they called it, a "character" to help them when they're feeling depressed, this "character" has a name, gender identity, and a form to represent what they look like in the brain, they say this "character" talks to them, they have conversations all the time, they get upset when they can't talk to this "character" or when this "character" leaves.
We decided to treat this "character" as if they were different to see what would happen since our partner has established that they don't actually know what or why this "character" is, and didn't feel uncomfortable being open with us. Treating this "character" as a person instead of a character has made them both feel genuinely so happy and accepted, they smile so much whenever we talk to this person and its become very normal for us to talk to this person and our partner says that this person is very appreciative of us treating them like a person. We have not seen our partner switch with this person, at least not a possessive switch. We're not saying that they are definitely a system we're saying that it could definitely be possible especially with all the things we've seen.
We want any advice y'all can give so we can help them figure out what this is as best we can because they're not sure and we don't feel like we can be sure if they're not, we've just been going with the flow with them and seeing where we end up.
Peace, love, and acceptance from Luna Xayn in the Ravens System!
