I've had experience with both handlers and narcissists in my life. They suck.
Narcissists are the worst. They don't have programming, just an agenda to suck the life out of you to keep them going. There is really nothing you can use against them except to leave and never look back. They can pretend to be nice, until they figure out you are onto them. And once you let it slip you know, they will never be nice again.
Handlers are something else. They are people with alters. One alter actually loves you. The other is programmed to keep you on a specific path. So there is a rocking back and forth between the behaviors. They will be kind and loving, until you step out of the path. And then they will do what it takes to get you back on it. Once you are back on the path, they will be loving and kind again. And not remember the crap they pulled.
You should also understand that all of us go through a period where we doubt everyone around us. Because what we are going through and obsessing about is so far out of the norm, we do legitimately worry our mates. They just want their old partner back. And while we are scared, it looks like handler behavior.
What you described about your husband crying, that is actually normal for a worried husband of one of us. I would be more worried if he hadn't cried. Your comment actually hurt him. Narcissists can't be hurt.
