I have virtually eliminated the word, "should" from my vocabulary. I believe this word, consistent with the tenets of cognitive therapy, creates a controlling, judgmental dynamic. Thinking "should" about someone you love or being on the receiving end of a "should" creates negative energy and, over time, can be toxic for all relationships, especially loving ones.
As described in my book, Why Can't You Read My Mind?, if relationship partners harbor internalized, hidden toxic thoughts, reflective listening drills may not expose these underlying empathy depleting thoughts. For example, if a partner is saying "I need you to please pick up after yourself more often", yet inwardly thinking, "You are always gonna be a lazy slob" then paraphrases will likely not rid this toxic underlying belief. For a toxic thinking partner to benefit in this situation, he must first be willing to challenge his toxic thought. In this case, the way of disputing the toxic thought may be, "She brings me a lot of joy and loves me deeply but rigidly and disrespectfully expecting her to be neater is not fair. It will help me to remind myself that she is a very nurturing mother to our kids, cooks well, and really is sweet to my family."
