^^ This. People will have their own ideas no matter what. I find what works best for me is to just NOT be secretive. That means not exactly coming out but just being normal. I mean it's normal for me to talk about something and say "Boyfriend watches that show!" or "Oh yeah Hubby and I do that on weekends with the kids." Some people pick up some don't. If they ask, I clarify, if not, then not worried about it. I get most often "You mean ex hubby right?" Then I clarify. Making it just a normality in my own life does a pretty good job of letting others know that it is indeed just normal! At least for me.
