My marriage counselor doesn't do schema therapy, but he has talked about how some of why I feel and act the way I do is because of schemas, generally from childhood. It's helpful within marriage counseling because it can help explain why I'm reacting a certain way to my husband, like why I'm expecting him to be mad at me for something, would reject me for something, etc. (because of how my parents reacted when I was a kid--or even now, etc.). So it helps both me and my H understand more. I'd like the idea of trying schema therapy, though don't think my T is trained in that.
