Absolutely! After many years together, there comes a time when it seems you know each other so well you can finish each others sentences! And it’s easy to begin to take each other for granted.
One thing you could do to let your wife know you love and appreciate her would be to take your wife to a quiet restaurant (with your cell phones turned off!) and read her a love letter you have written her.
Or, bringing her home a small bouquet of flowers on an ordinary day will make her feel special, too. Whatever it is, it’s important to remember to do something thoughtful and unexpected for each other on a consistent basis.
