Most people feel that conflict is something to be avoided at all cost. In relationships conflict almost always eventually happens.
Conflict can be the source of deterioration of the relationship or the opportunity to grow closer.
Honestly revealing ourselves and being genuine gives a feeling of ease and trust if we are accepted as is, with all our warts. We often feel that if the other person really knew how we feel, or who we are, that they will no longer like us. This is a universal feeling and usually erroneous. There is some basis to this fear. As we develop relationships we tacitly agree to act in ways consistent with the way the other person sees us.
