Overstepping boundaries

My MIL took my son on a little roadtrip yesterday. MFH's sister and her family are moving to Alaska for two years, and they brought all their worldly possessions to Wyoming to store. The Boy got to spend the day playing with his cousin, and that was great.

We met my in-laws for dinner last night to pick up The Boy. Right at the end of dinner, he said, "Mom, what is my real name?"

I said his name, of course.

"No, I mean my name in Guatemala."

"What are you talking about?" I asked.

"Grandma! What was my name in Guatemala again?"

And she smiled, repeating what they had obviously talked about earlier.

In what world was that information hers to give?

I said, "We are leaving. Your name is -----. Let's go."

As adoptive parents, it is our responsibility to share his story, and we feed him as much as we want him to absorb at any one time. There are parts of his story that our parents know that we may never want him to be told. I have been sorry for a long time that we shared a lot of it with our families, and I would take it back if I could.

I wonder to whom else she has blabbed his story?

MFH needs to address this with her.

I am so angry.
