I was open from very early on ...about being a crossdresser. This was accepted without question. It was not until therapy helped me realize that I was something other than a CD that things got tougher. She is still supportive, but I can tell that is a struggle, at times. Her kids know. One is totally "meh", and the other wants to hear nothing about it. Open and honest communication is often hard (believe me, I know) but it is an absolute requirement if a relationship is to survive.
