My husband, in this altered mindset, is hurting others through an intense need to control ..... like an ownership ..... but of course he doesn't / can't see it that way.   And he switches to being playful, charming, loving .... while the person is captive to his wishes, if that makes sense, becoming hostile if they are uncompliant.  This appears to be a pattern within his family though, so I am assuming a personality disorder rather than plurality.  

WH wasn't like this before, although there were attempts at this sort of behaviour early in our marriage and we had to sort them out, because I wasn't prepared to live with them.  At the time I thought it was learned behaviour from his family environment. 

And he has issued a threat, hyperthetically, against anyone who would harm one of his kids .... which I have to presume was part of a delusional state.

Wow .... 60 .... ❣️   Do you find it difficult to give them all time ?  It might not work that way .... I imagine all are busy within the same internal space in their own ways .....

I found it hard to connect with the DID label too .... it's not a comfortable fit to my thinking either.

Please let me know if I am challenging any of your boundaries unintentionally ....
