I’m going to make a paradoxical statement here: The purpose of marital counseling is to have individual counseling in the presence of your spouse.
All marriages are made up of an uncountable number of reciprocities. That is, you and your spouse (and others in your relationship triangles,) react to one another over and over again in patterned ways. These patterns can get stuck and, in some cases, dysfunctional. The goal of therapy is to figure out your part in the reciprocities so that you can make modifications. This can be done with your husband present or without him.
