Ahh yeah I do get what you mean because when me and my OH were only friends I had a boyfriend that I couldn't tell and he saw one message from my now OH and he thought I was cheating on him with my then CD friend and it was a bit awkward trying to explain to him that no im not cheating its just that he was a CD'er and the message was completely innocent, so I do get how you feel, maybe you could try and talk to your OH and explain that you would feel better if you could talk about it to your friends and family? Just try and give him that bit of confidence to be more open about it? I know how hard it can be with the secretive side to it so the best you can do is support him and hope that he becomes more comfortable with it, enough to start telling well trusted friends, im lucky really because my OH has told all my friends and family about it so we are more open with it, its just annoying that CD'ers think they have to hide it because of what society is and isn't accepting of
