Hey rotiroti,
I can understand how frustrating it is when we're cutting off all communication avenues. You're ex knows this.
It sounds like you are split white if she only has good things to say about you. Something similar happened to me, although I was split black and my ex sent an email to my mom telling her how awful I was treating the kids. Fortunately, my mom understands BPD
Beach_Babe has good advice.
How would your parents respond if you told them to bin the letters and not advise you that she's sending letters?
Thank you both!
You know my parents would support me 100% no questions asked. It's strange how all of the gas lighting and belittling makes me second guess my intuition on things like this. Thanks again (and honored the Mutt replied!)
