Marriage Counseling could form part of Family Counseling. The difference is that Family Counseling could involve other players in the family too besides the marriage partners and may include various other issues such as Youth issues, abuse of women and children issues, issues arising on account of substance abuse and addiction, etc, besides marital issues. In particular in family counseling the effect of the interplay of various forces and players have to be considered too. On both Marriage and Family counseling, I would adopt specific unique strategies to meet the needs of the situation to resolve problems and remove the knots. Talk to me to gain a better understanding on this.
