It's interesting that when some people are sitting in the therapy chair they think the goal is to convince everyone that things are actually OK. I think part of that is they simply can't bare the idea of being seen to not conform to the rigid (yet superficial) social expectations.
Therapy or affair? They both spell the same thing. Over. One perhaps more efficiently than the other. By that stage the weighing up of "rights" and "wrongs" is of little use.
