My suggestion is to try a short program with the group before making the decision to invest in the long course privately. The group provides energy and a safe atmosphere for taking risks and trying new behaviors. It shows participants that other people are really more similar than different. It shows participants that the work of relationships is hard, but do-able. The design of the curriculum and the psychoeducational modality enables all sorts of different people in different situations to grow and learn and change.
People are usually of all ages.
The older people usually say they are envious of people who take it while they are young because it provides them with skills to use to have many, many years of happiness. People have made important decisions, have grown and bonded together in healthy ways or have been able to leave relationships that are not fulfilling and bonded. Countless marriages have been saved. The success rate is highly impressive. My grown-up child is planning to get married.
