Try to write a note to your wife everyday but give yourself grace when you don't. She will know your desire over time to do good to her. Oh, and don't worry about running out of ideas. The more you write notes to her, the more the ideas will come. In addition, text messages and picture messages can convey your love for her as well. One time, I sent a picture of a male and female tiger snuggling with one another. I attached the words, "I love you." It affected my wife greatly. Sometimes, a text that simply says, "Thinking of you," is all that's needed.
