Treat her like a queen...

Buy your wife something unique that will make her feel like a queen. It doesn't have to be expensive, just something thoughtful that shows you are thinking about her and that you care. This may require some recon work and carefully crafted questions to find something she would like. Do the work to make it memorable.  

Let her know you are glad she is your queen. Her favorite body lotion, a manicure/pedicure, costume jewelry, perfume, check out Groupon for other ideas.
