How we communicate is the problem more often than what we communicate. If the ways you communicate do not work with your partner, then your messages of concern, hope and love may not get through. Without clear communication, we cannot make our needs known and cannot negotiate to meet them. This means we must genuinely consider the feelings of our partner as well as our own. If our words are not moderated by tact and sensitivity, then our partner's reactions may block the message we intend to send.
Relationships built on lies are like houses built on quicksand.
Eventually, they sink. What gets in the way of direct, clear, specific, honest yet tactful communication more than anything else is our own history. Some of us learned to be tactful. Others learned to use honesty without empathy to aggressively control those around us. We all learned from our families as well as our other unique life experiences that certain ways of communication worked.
