Excellent, Ravens. Therapy can do amazing things. Good advice here so far. I would add that if you feel things aren't working after a session or two, don't be afraid to get a second opinion - in other words, a different counsellor. Sometimes personalities don't mesh well, so you have to keep trying until you get the right one. Don't give up on counselling, though.
Also, try to avoid the tendency to highlight anything the counsellor suggests that might apply to your wife. Keep it self-reflective and apply what you learn to yourself. Model that attitude after each session, i.e. "today I learned that I should work to be better at xxx etc." or "I'm going to try and follow the counsellor's suggestion in xxx" You can also say things like, "I thought the counsellor had a great idea about us working on xxx. What do you think?"
Good luck. You are doing the right thing.
