With my ex I had after one session left something in there so went back in, counselor said your best leaving her. I was taken aback at the time but she was right, just did not see it. So it was in some way pointless if saving relationship was the idea. I have been told a couple of times that the main purpose of it is to help couples come to terms with the end of their relationship. Don't know how true this is though, but it seems quite logical, perhaps people should go before they get married?
