It can work but both partners need to realize they need to change and be willing to commit to making it better. We have done marriage counseling off and on over the last few years and it has not really helped us for that reason.

Also, our T was our marriage counselor AND our individual which was helpful because he knew us both really well. He did have a "no secrets" policy so if it was something big, he would disclose to the other but only after giving you a chance to come clean first.
