It is ok....but in reality your old therapist would contact your wife and make sure the confidentiality waiver between the two of you was still good before contacting you. I would assume that at this point your wife would say "no" it isn't and that would be the end of the conversation.
Do you have a list of YOUR shortcomings? That is a good place to start. When you accept your own shortcomings you will be more successful in conquering them. Some shortcomings you might look at as strengths, but from the outside they are weaknesses. Me for example-I worked to much....did it so the family was financially secure, so I thought it was a strength that I worked so much for the benefit of the family. Reality was that I was not spending good quality time with the kids, getting enough done around the house, taking care of myself, or taking care of my relationship with my wife...all because I worked so much. But working so much was justified in my eyes. Sometimes the things we think are great for everyone are just illusions we want to see.
