Maybe she'll keep it up.
Tuesday when SO took the kids back to their moms he was gone for longer than normal. He came back and said they had talked about a few things. BM admitted that there is another adult female living with them and shared how the relationship works. She asked about the details concerning our home and expressed worry about the current room arrangements which were valid. She asked about me because my work hours had been keeping me from the kids.
Basically he was confused because they had a normal talk. He said there was no hostility. She even gave him some school pictures of the kids this year since we missed our ordering them because all the issues with the start of the school year.
I'm really hoping this maintains. I know shes been easier to communicate in text for a while now.
