Welcome to our family,
Thadeous!
It sounds like you have your hands full with the behaviors of your mom and her duplicitous actions. It is very common for pwBPD to split their children black or white. It was much easier for me to see it take place when I read about other's situations than to see it so plainly in my own life, but once I began to take a serious look back, I could see how frequently my uBPDm would split me black too. Sometimes I was white, or the golden child, and my siblings and I regularly rotated through those stages which she assigned to us.
I'm very sad to hear that she continues to be so demanding and controlling of you, even as an adult. Thankfully you were able to set up and maintain a boundary regarding the phone, but it sounds like she has shifted the demands to email control now. Do you feel that she is emotionally dependent upon you? Is your dad supportive of her or of you or are you unsure where his loyalties lie?
I'm getting increasingly annoyed at being half cut off from and financially manipulated but why should I loose that income due to her manipulations? It's a shame as the money manipulation sculldugery was why the phone calls had bad undercurrents in the first place.
Do you feel that she is manipulating you, pulling the strings, and you keep going along with things? I hear you saying that you are getting very tired of all this, and I can see that the pull of the money is greater than the difficulty in putting up with her, but that is beginning to change for you. What options do you feel would be healthiest for you? Unfortunately BPDs cannot be changed, but you can change how you respond to them and find greater peace yourself through the process. Here is a link with some thoughts that may be helpful to you:
