You and your spouse have decided to divorce. One of you has moved out of the house. Maybe you've started the legal process. Amidst all of this, you're going to need to tell people about it -- family, friends, co-workers, people at your kids' schools and others in your social and professional circles.
What you say and how much detail you provide will vary depending on whom you're talking to. That's one reason why sharing the news via Facebook or other social media platform isn't generally a good idea. Further, even if your post is only seen by Facebook "friends," you're still inviting responses, and they may not all be as supportive as you hoped.
