"No longer say 'I love you because....' Say 'I love you period.' "
"Do something out of the ordinary today for your spouse. Something that proves (to you and them) that your love is based on your choice and nothing else. Demonstrate love to them for the sheer joy of being their partner in marriage"
Has your love in the past been based on your spouses attributes and behavior or on your committment? How can you continue to show love when it's not returned in a way you hope for?
