SHE NEEDS TO SEE AND HEAR THAT YOU CHERISH HER AND THAT YOU DELIGHT IN HER AS A PERSON 

To Cherish is to see great value in a person that you want to protect and also to praise to others. 

It is important for her to know that she is a vital part of your world and equally important that your delight goes beyond the things she can do for you. 

SO – Grab a cup of coffee; find a quiet place for a time of reflection and prayer. Ask God to clarify for you the things that attracted you to your wife (character qualities / personality traits / etc.) and the evidences of God’s leading that brought you together. 
Make a list of things that come to mind. Then set a aside a quiet time with her and share that list with her. She needs to hear your heart. 

Guys! Let me know how this goes! – Bill Thompson
