Mine 9 year old us afraid of the dark

My husband feels that he is acting like a “baby” a “girl” and that this behavior isn’t normal. We are constantly at each other throats over how he speaks to him. I’ve given him my phone flash light and he tells me I’m undermining him. It’s normal for a child to be afraid of the dark and my husband behavior isn’t normal.

I am being told I enabling him but I think he’s emotionally abusing him. Am I wrong?

Mild disclaimer: my child does have a listening problem.
