1. Gratitude
Your man needs to feel loved. He needs to be important. Men can be quite sensitive. Pet him. Let him roar as the Lion King. In small ways, let him know how grateful you are to be in his life. Every little attention that you give will go a very long way.
2. Listen
Few of us actually do. This is the simplest and most effective of any technique. There is always something new and interesting about someone you know very well. Just listen for it. When you truly listen, you are placed in an attitude of curiosity and wonder.
