Here's my 2 cents. If any S says she is willing to go, then GO! You have no idea what her motivation is but if counselling could help the R then do it. I would advise looking for a Solution Focused/Oriented Counsellor as they are trained to help you look at what you want rather than how everything went wrong! Nobody wants to sit around and discuss their screw ups, it tends to make repeat visits unlikely. The Solution Focused approach is respectful, looking to the future and how you, as a couple, think you can get there. I'd go for it.
