Life sometimes teaches us, it is best, or easiest, to keep aspects of our past or other issues from our partners. Some things we may never reveal so maybe an important part of us stays hidden. We may also feel uncomfortable in sharing parts of a partners life, that hasn’t been shared previously, things from childhood or old loves, old relationships emotional feelings.
In order to be open and honest, the relationship has to feel safe and supportive. Buried issues, feelings of inadequacy, stories of good times with others can only be shared to a partner who will listen and not judge; who will not use the information shared spitefully in the future.
Revealing aspects of ourselves that we normally keep hidden, and exploring them with a partner, is true intimacy.
