H knows, and my kids kind of know (but are really not interested). I have sat down to dinner with H and said things like "Oh, Lola's stray had her puppies, so cute". (Well, and maybe I said "can we drive across the country to get one"...lol.) He has forums he likes to visit as well and he brings up those people on occasion. Quite often we are sitting next to each other on the couch with our respective laptops open. One of us will chuckle at something and the other will ask "what's so funny". He doesn't usually get therapy jokes though.
