On another forum, I posted pics of me my my boyfriend (who's a member on that forum as well) and my husband was the first to post a comment about how we made a good couple. I think one person asked a question (wait, weren't you married to someone who isn't him?) my husband answered "yep, that would be me" and that was pretty much the end of that.
People have been referring to it here and there but there was no explosion of anything, no judgement, no nothing.
And now we can be open on that forum that we all frequent, which is pretty nice.
