I have told my family and close friends, most of my close friends have had wls. I am not broadcasting it and have told my children it is not something they need to tell their friends. It is a personal issue and if you want to tell people, it is your choice to do so. I am not ashamed or embarassed by it, I didn't go and tell everyone that I had a hysterectomy either. Medical issues are a need to know basis type of thing. As far as your husband is concerned, you do have the right to be upset but don't hold on it the feeling. Talk it out and let it go, I am sure he knows he shouldn't have told, that's why he told you a few weeks after the fact. Just remind him that what he did was not very nice and ask him to not do it again. Stress and anger can mess with your weight loss. So stay positive and keep moving forward =0)
Good luck to you !!!
