I can't offer any advice but I am really curious to hear if there are any helpful suggestions on dealing with an ex who has BPD. We are going through the same thing, and it is unbelievably difficult to co-parent. It's nearly impossible for him to have a conversation with his ex, and I have never in my life dealt with someone who is so mentally unbalanced. I have zero communication with her but she is consumed with finding ways to hurt both of us. The only thing we have learned to do is the same that you have been doing - document everything! We have had to file numerous police reports due to her violating the restraining order he has against her, court orders, etc. She keeps getting in trouble with the courts but cannot control her impulsiveness. Anger controls her. Unfortunately their children are exposed to all of this, and even with her violent history, they still share custody. She has been working very hard at turning the children against their father, because for her, custody time = money. She refuses to work. The children are becoming very confused due to her "stories" about their father. He just started therapy with them again. She refused to take part in it and blamed all of their problems on him. I think it's typical for a person with BPD to blame all of their problems on everyone else. Her explanation to the kids about her violations of the orders was that she wasn't doing anything wrong, their dad is "harassing" her!
They can't communicate via e-mail (which would have been best) because she told the judge that she was worried he would send a virus to her computer. So he is forced to have conversations with her, which generally are nothing but screaming and yelling by her. I suggested he text message her, but she won't respond in writing. My opinion is she knows anything in writing could be used against her, so she won't leave a paper trail. If anyone can offer any suggestions on how to better deal with this, we would greatly appreciate it. It's just amazing how emotionally draining this had been.
