My mother-in-law blamed me every day for not being able to have a child. But one day, once again, while cleaning the house, I found documents

While they were away I packed up all my things, when they came they didn’t understand what was happening. I said I knew everything and I wouldn’t live like this for another minute.

My mother-in-law came and asked me for forgiveness. She asked me to return to them, but I was adamant that after everything that happened, it was simply impossible. What do you think about this situation? Did I do the right thing?
