It's the simple things that bring a smile to your wife's face. Here are 15 things you can do every day to melt her heart:

1. Kiss her in public

Don't shy away from showing affection in public. Kiss her when the moment is right. Even if you like to keep your love private, an occasional spontaneous kiss in public will remind her how much you love her.

2. Rub her back

Treat your wife to a back rub. A massage will help her relax from the stress of her daily responsibilities. For extra points, rub her back as she falls asleep at night.

3. Ask her how you can help

Make your wife your first priority by asking what you can do for her. Serving your love will make her day a little easier and put a smile on her face.

4. Let her splurge on something she wants

Did she do a double take when she noticed a dress at the mall? If you have some wiggle room in your budget, let her treat herself. Adding a new outfit to her wardrobe may be the pick-me-up she needs.

5. Turn off the lights at night

This is the simplest gesture, but turning off the lights when she's already snuggled comfortably in bed will make her heart melt.

6. Pack her lunch

The few minutes it takes to pack her lunch will give her give her a little more time to do her hair and makeup in the morning. She'll appreciate your sweet gesture for the rest of the day.

7. Go all out for dinner

Make her favorite meal and set the table while she kicks her feet up. She'll appreciate being able to unwind at the end of the day. Bonus points: leave her a sweet message with her meal for an extra (and adorable) surprise.

8. Talk to her in bed

Don't spend your last few minutes before bed flipping mindlessly through your phone or checking your work emails. Those things can wait for morning. Set aside distractions and have a meaningful conversation with your wife before turning out the lights.

9. Leave love notes around the house

Hide love notes for your wife to find throughout her busy day. Leave one on the bathroom mirror, in her purse or on her pillow. You will make her day so much more enjoyable.

10. Help others

Even though helping others isn't something you do specifically for your wife, she loves seeing you serve other people. Your selfless acts of kindness are a great example to her and your children.

11. Read to your children

Read to your kids before bed and find time during your busy day to play with them. You'll bond with your little ones and make your wife love you even more than she already does.

12. Spend time with her family

Make her side of the family a priority by spending time with them. Don't shut yourself out - you're part of her family, and she wants you to love them just as much as she does.

13. Introduce her as your wife

Introduce her as your wife and by her first name (not just by her name alone). This simple word choice shows her you want everyone to know you're happily married.

14. Reach for her hand

Don't forget the simple gestures. Hold her hand and kiss her on the cheek to give her endless butterflies.

15. Tell her she's beautiful

Don't wait for her to ask, "how do I look?" Tell her how gorgeous she is. Pick specific features to compliment like her hair, her eyes or her smile.

These sweet gestures should never replace the power of saying, "I love you" but they are a meaningful way to prove how much you adore her.
