You said that you were going to have a tough time dealing with your mutual friends and letting them in on the little secret the two of you share.
Let me tell you, they probably already have guessed something is going on, and.........you have it easy my friend.
Take a look at what I had to deal with. You might have an understanding of the male dominated and not terribly educated environment I work in everyday. It doesn't take a rocket scientist to do what I do. Any person who can repeatedly do the same thing over and over again can do this "job". And it's male dominated. In that environment, I met my wife at work. And that was extremely tough for both of us. What with the cat calls my wife received from other guys (and still does) and me having to force myself not to crush every guy that became "friendly" with my wife, and all the innuendos that guys were wanting to hear about my wife and I, I think you've got it pretty easy.
So chin up, let your friends know and take your short lived lumps. If they are good friends, they will support you and relish in the fact the two of you have found one another.
