Your first step is to ask yourself why you would want to tell them if you already know what their reaction will be. I think it works much better if you let them figure it out for themselves. That will give them time to absorb the shock gradually. If a person has time to suspect something for a while, they deal with it much better when they finally learn their suspicions are in fact, true. Otherwise you are setting yourself up for a lot of drama.
