My H. He is my reality check, thankfully. He can tell by now (we've been together 30 yrs) when I am "off". I also have learned to ask.
"Did you see that?"
"Did you hear that?"

Even my adult children will at times say, "No worries mom, I heard that too".

I have found it crucial to make a list of people I trust and carry it with me. It's a very short list, but it reminds me the H tells the truth and would never let harm come to me.
