The act of spilling your guts can have both a positive and negative effect. Positive if you get something out in the open that's affecting your relationship. Negative, if you get it all out there, and still no appreciable change in your partners attitude or conduct. This lead me to feeling even more hopeless/helpless that any real, longlasting change was possible. So, in the end, it had an overall negative effect. But I was glad that we gave it a shot. It has helped many,many couples.
