My boyfriend is OCPD or is diagnosed as such. I myself am schitzotypal, so I can handle quirks. I have not been able to find anything on the internet about his most prominant "symptom" however.
He mutters under his breath and sometimes it is terrible things like "i am going to kill you" or "kill yourself" or "stab you" or "kill them all" or it can be totally nonsensical like "chicken pants" or "baseboard" or some other seemingly random phrase. Sometimes when he says something awful like "I am going to kill you", I have responded and he has been embarassed and apologetic so I know this can be troublesome to him as well.
I guess I want to know what is going on inside his head - it often sounds like a continuous dialogue that I am only privy to parts of.
He says he doesn't know what he is saying, but sometimes he hears himself.
In public he mutters quietly, but at home and around me he is more comfortable I think, and so it is more prominent.
He is a really nice guy, with social anxiety, I know when he is stressed out or tired it happens more, so he isn't able to control it as much.
I would love to hear from someone who mutters to tell me what is going on from his point of view.
Any suggestions or help is appreciated.
