gottafixit,
I can rekate to your frustration.
I have to have contact with my ex because we work together. I have found the communication lessons on the staying board to be a great help to me.
https://bpdfamily.com/message_board/index.php?topic=69272.0I am new at this so I am sure some of the senior members will have more to add. But I am learning that I can't help my ex, (or predict how he will act on any given day) I can only help myself and these tools have been very valuable to my mental health.
