Sympathetic Joy.....

Who is the happiest of man?  He who values the merits of others and in their pleasure takes joy, even though it was his own.~ Goethe
So you want to have a better relationship?  How about trying out sharing positive feelings for the successes of others.  It is important to celebrate the successes of others especially in a romantic relationship.  This adds the cement to the foundation.  It is important to be happy about the others success and be enthusiastic and not competitive or envious.  It is also important to take the time to find out the details of success and show respect.  We need to give our time and care to the benefit of the other.  This will create a bond that will help the person when life starts throwing curve balls and we can't get out of the way.  We need the support of others when life gets difficult. 
One of the things that gets in the way of relationships can be envy.  We can starve a relationship with this reaction or we can become aware and find a way to communicate this negative effect.  This will clear the way for the positive support that we all crave.

LENS neurofeedback can help us to work through the suppressed emotions.  It helps to get the unconscious, conscious.
