Scenario...

You're dating a guy seriously.
He hardly ever sleeps over at your place.
To be honest...his place is FAR nicer than yours and he's used to living the way he lives.
You ask him why he never wants to stay at your place and he says he's just not comfortable there.
You press him and he admits that your level of cleanliness in your home is a major problem.
What do you say?
What do you do?
