I was in couple's counseling briefly with my husband. He also was very briefly in therapy on his own. He was extremely introverted. He hated telling all this private stuff to a counselor.

One day, I told him "You don't have to go to therapy. I don't care if you go to therapy or not. Therapy is a means to an end. Therapy per se doesn't matter. I only want our marriage to be better. I don't care how that happens."

So he quit both his own therapy and couple's counseling. And he was promptly and permanently a better husband.

There are many paths.

Great point. As a fellow introvert, I think I would also be better off.
