Consider what it says about you if you deed over your soul to one. Truth is the first thing necessary to create trust in our relationships. Respect is earned from trust, and love is earned from respect. Intimacy is the gift we get when we risk telling the truth. See the hierarchy of a functional relationship 9.
Fear of intimacy is fear of the truth.
Your truth is better for you than someone else's. Just get to know what it is so you can own it. If your relationship is not getting better, it is probably getting worse. Life is dynamic and nothing ever stays the same. Every relationship is unique.
