With many people, the opposite is the case. Work interferes with the relationship. Suppose work is 8 hours per day, but there is also 8 hours of housework. If you split evenly, which isn't normal, that gives 12 hours per person with you both working outside the home. That goes down to just 8 if only one person works. You then have more time for the relationship.

You might need to make a cultural shift. You'd need to show appreciation for housework. If you're in the habit of looking down on people who do that, or if she herself is, then things won't go well.
