To answer questions:

He's having blood work, a brain scan, and a sleep study. Doctor thinks it could be as simple as his blood sugar being off (he's diabetic) or sleep apnea, both of which can affect concentration. It's going to be a while before we see results. It's even going to be more than a week before we can schedule the brain scan. And that's on the "urgent" timeline.

That's another thing. At first the doctor had scheduled it on the "normal" timeline, which would take even longer to get it to happen. Then my husband told him what happened at work, and the doctor immediately bumped the tests to the "urgent" track. "I didn't realize your job was being affected."

It's OK to have the marriage affected, but we CAN'T let it cause problems on the job! The job is SO much more important than the marriage! Why is that?

On the other hand, this happens too. I say something, and he gives me no indication that he even heard me. He doesn't look up, doesn't nod, doesn't say a word. So I'll repeat myself, and he says, "I heard you the first time."

If he doesn't acknowledge me, how am I supposed to know he heard and understood?

If he acknowledges me, how am I supposed to know he didn't hear and understand?
