I would lump physical and sexual intimacy under the same umbrella and then emotional/mental intimacy under another.

I think YOU are getting there on the emotional/mental side. Your wife too a little but it seems for her the physical/sexual is required to complete the package.

Not sure I am explaining it that well. You seem better with mental then emotional then perhaps physical and then sexual in that order.

She might require the physical before she feels complete on the mental or emotional side.

You are on the path. At some point it may require a simple leap of faith...but that's easy for me to say. I'm not the one leaping.
