My husband knows. It always used to be such a big deal, but then we were both trying to lose weight and decided to start a contest, so I had to tell him. It was so hard, but he didn't care one bit. He sees me naked, it's not like knowing the number really makes any difference.
It's nice to be able to share my specific number goals with him too, to have someone in real life to talk to about that stuff. Funny thing is, I still won't tell my mom or my sister, not that either one of them have asked. I've also been thinking about if I want to disclose my highest weight once I lose a bunch. Do I really want people to identify me as a specific number? It's funny how we all have different opinions on who should know this kind of info.
