Hello
CalifMomto2 
Welcome to the family! I'm so sorry you had to find us but I'm glad you did. We are all here because we are experiencing similar feelings and situations and we support each other as we learn more and navigate these tumultuous relationships.
I had made great progress in setting healthier boundaries, being validating and learning how not to trigger her better.
Sounds like you're ahead of the game with this, great! Validation and boundaries are so important - are you working with a therapist who is educated in BPD?
She kept screaming at me & vowed to never let me see the baby because she could “no longer trust me.”
Ouch! I bet that hurt so much.
When she is verbally abusive or hurtful, telling her only enraged her more. She openly says she does not care how I feel.
This sounds about right. When a person with BPD is in pain, they'll do whatever they can to get rid of that pain; usually placing it on those closest to them. I know how awful it is to tell someone I'm hurt by their actions and to hear that person tell me they don't care.
Do you have any outside support from family and friends? A therapist of your own? We talk a lot about self-care here and it sounds like you are in need of that right now.
I was so looking forward to being a grandma but I can see I’m going to have to change my expectations and coping strategies.
Thank you for the reminder to "
change my expectations." This is something I must keep in mind every day with my daughter. We have such high hopes for how our relationships will be with our adult children and their children. When things go differently, it can really pack a punch, can't it?
Have you had a chance to look around the site? Here's a good place to start:

We look forward to getting to know you,
