The greater the trust within the couple, the greater the opening to share in love.
There might be a lot of physical chemistry within a couple, but without the compatibility of life philosophy and interests then the relationship will likely not be long-lasting.
Communication within the couple includes the open, clear, and honest sharing of feelings, desires, thoughts, interests, and creative ideas. It is in this sharing of the deepest parts of ourselves with another that true intimacy in the relationship is cultivated.
