How Many People Are In Your Relationship?

Do we allow too much input from friends and fam in our intimate relationships? Sure, we all need a sounding board from time to time, but are we sharing too much? And to make matters worse, are those with whom we share then giving us more input than is necessary? Do we find that we are saying and doing what others tell us to in our relationships that we would not typically do ourselves? Are we betraying our partners with what and how much we share? Are other people intervening in our conflicts, even to the point of speaking on our behalf? Are there more than two people in your relationship?
