A few years ago, I would have made any girlfriend I had a public thing.
Now, absolutely not. I think announcing it to the world (up until the wedding invitations) would just dilute how special the relationship would be. And if it was one of you CC ladies? I would most definitely want to keep it hush hush in case it doesn't work out. I don't want to announce the headline, "SGT. SCHULTZ AND MISS DOE BREAK UP, MAN CLAIMS HE KNOWS NOTHING"!
