I've never been a fan of couples counseling, I don't know of any instances where it's been effective. I don't know, some guys here are advocates of counseling, so I guess YMMV.
I went to couples counseling once. It was after, as I've mentioned before, I had accumulated a significant amount of credit card debt without my partner at the time knowing about it. The way the counselor explained it to us was that the original foundation of the relationship had already been built. The purpose of counseling wasn't to restore that original foundation, but to build a new one on top of it: one based on new boundaries, routines, trust, responsibilities, and expectations.
The problem is that both parties have to want to rebuild the relationship. However, the person who was wronged and had their heart broken will often have a long list of new terms, conditions, and concessions. Meanwhile, the person who did the wrongdoing will have to give up a great deal of their own freedom, comfort, or habits just to begin the healing process.
I've only done superficial research on couples therapy, but one of the main studies I found indicated that 78% of couples therapy cases (roughly three out of four) are initiated by women. Likewise, around 70% of divorces are initiated by women. Those statistics alone don't establish who benefits more from counseling or who is at fault in any given relationship, but they can help explain why Rollo's Rule 7 states,
"Time and effort are always better spent pursuing fresh prospects than trying to fix a failed relationship." If rebuilding the relationship requires starting over from scratch, it becomes easier to argue that men, in particular, may be better off not attempting to rebuild it at all, but instead investing that same time and effort into a new relationship.
