I think it is your therapy and he should be dictating who you have to tell things to. My T seemed surprised that I wasn't telling my husband I was coming to therapy. I didn't explain it, I had my reasons and they were valid. I wasn't lying to him, just not accounting for that hour of time. There have been times when she has suggested that I speak with him about certain issues, but she has always left it up to me to decide if and when those conversations occur.
