Tell your wife you've planned a very special date. You've taken care of all the details and it's all a secret.

Take her to a store and put her in the dressing room and pick out clothing for her to try on. The entire outing can be really fun, especially if you praise how beautiful you think she is in whatever you've picked out.

Buy her an entire outfit, from dress to underwear to shoes. If you want to top it off, offer to have her hair styled and a manicure and pedicure, then take her out to a romantic dinner. Make sure you look really nice, too!

She'll feel beautiful and spoiled by you. Tell her how much you love how she looks! You may find that it changes how much effort she puts forth if you re-ignite a spark there.

If it doesn't work, you'll still win major points for being a great husband and for appreciating her. It's a win-win situation.
