Welcome
Chronsweet!
So glad you came and shared some of your turmoil with us! You are welcome here with us, those who understand what you are going through. I am really sorry that you have gone through this and still are. It is tough, beyond hurtful, and so tiring and exhausting. You are among friends who will share thoughts and experiences which I know you will be able to relate to. My mom was also an uBPD.
I look at my child and imagine calling him names, invalidating every feeling he has, being as un-reassuring as possible, putting him down and making him feel inferior, always having to win every argument, not being able to talk without screaming and hurling insults, and I cannot even imagine doing that.
This is a very astute observation on your part, and I am very glad that you are able to grasp the truth of the incredible difference between the choices you are making and those which our moms made. You and your son will be so much healthier!

Other members have gone NC, and hopefully they'll pitch in and share their thoughts about it. I was very LC with my mom over the years because she lived many states away from me. In retrospect, I didn't even know what BPD was, that there was such a thing as NC or LC, but I see how instinctively I knew I had to keep some boundaries up around myself and my family. I am so glad that I did.
Have you read some books that have been helpful to you about Borderlines?
