I Excluded My DIL’s Kids From My Family’s Gathering

I almost fainted when I opened it and saw all my belongings from my son’s house, where I occasionally stay. There was a note saying, “You’re not welcome to stay at my house anymore.” Sh0cked, I chose not to react to avoid creating further conflict.

However, the next day, my grandson called me in tears. He told me that his parents had a huge fight, and his dad had left. I rushed to their house and froze when I found the place in complete disarray. My daughter-in-law turned to me and said she wanted to leave my son because he didn’t stand up for her kids.

She told me that what I did was unacceptable and that she would never forgive me for excluding her children like that. A few days have passed, and they still haven’t reconciled.

Am I to blame here?
