I just want to relate to experiencing sort of hot and cold behavior from my ex. It can be pretty difficult to cope with. Everyone's different and this is just pure speculation, but I thought I would share. I know my ex would often feel she was "too much" and be deeply ashamed and somewhat shut down at times after she shared things about herself. I wonder if something similar is happening here--shame and regret for opening up? I could be totally wrong, but wanted to share in case there was any similarity.
That's a good guess but I don't think that's it. She didn't tell me anything I didn't already knew except for the moving in part. She told me that because I now have to pick my son up at his place. I get an impression she wants more personal contact for reasons unknown
