Speaking from my own experience, 25yearsmlc is correct.
After my bomb drop, I told people things that I now wish I hadn't, because it's caused hard feelings among my wife and my family.
It's a passive-aggressive way of putting pressure on him, and you will make it harder for your husband to share his feelings openly with you if he thinks you are going to tell everyone he knows. Also, your friends and family may not want to know all of the details of what you went through, even if it looks like it might have a happy ending.
