Share some significant moments from your past with your partner. The open and expansive. Make sure you include enough details about these events to make the stories interesting, to allow your significant other to understand you more deeply or in a different way.
Did you once take a backpacking trip into the wilderness alone and find that the solitude introduced you to parts of yourself you never knew existed? Did you once spend hours a day humming melodies from Bach and Mozart, which inspired you to take up the flute? Did you ever help a friend or relative through a difficult time — like the breakup of a relationship or the death of someone close — and later find it was your support or encouragement that was crucial to that person's regaining peace of mind? Tell your partner what happened. Search your memory and relive the experience as if it just took place.
Try to tell the whole story from as many points of view as possible. If you are describing how you opened up a bicycle repair shop, tell your partner what your parents thought of the idea, and how your friends reacted as well. Ask him or her to listen carefully, interrupting only to ask questions about particular details or developments of the story.
It's often a good idea to talk about your significant past relationships, to discuss how they affected you, how they changed you, what you learned from them. If you allow your partner to participate in the storytelling by asking questions and providing feedback, he or she will feel closer to you, and you will have fostered that closeness by having opened up your life in a very intimate way.
