The problem is not the person you have the relationship with. If we look at it closely, the problem lies not in the other thing or the person, but in the relationship that we have with the thing or the person. That thing could be money, that thing could be knowledge, and that person could be a husband, wife, a son, a daughter, a friend, anybody. It is the nature of the relationship that is causing the problem.
You could be fully authentic and yet relate. Then all those relationships will obviously be authentic relationships.
