I have a supportive husband. He knows as much as he wants to 'bout my DID. But he continues to surprise me w/ how much he does understand. It's a tough thing to understand, even for us. I send him some links myself 'bout DID. I can't read them! too detailed, but I ask if he would at least skim them. He knows what he needs to, I mainly have him look at them so he knows I am not an unique case. That there are others like me out there.
I guess how to make it easier on him (& yourself) is to be honest & do what you did, send him info on this subject. Also what I found, try not to get frustrated when they don't get it. To me, how can people NOT understand me talking to myself, losing time, etc. But they don't understand 'cos they aren't DID. I have to learn patience.
Love,
RM
