Welcome, and I'm sorry you had to go through so much.
It could never, ever be about us. She knew more than anyone on any subject you could name.
I completely understand this one. I can only remember getting one true compliment from my uBPD mom, and it was because I threw a surprise birthday party for her. And don't ever try to correct her on anything even if it's obviously not true. She just responds with saying either I don't know what I'm talking about or I just think she's stupid.
I am used to being hurt and overlooked. But the grandchildren... . I don't understand that.
I also used to withstand the abuse, but my kids are the real reason I really started realizing this is not ok and I need to do something about it.
I invited her to the hospital to meet them as soon as possible.
My mom watched my first child when I was in labor with my second because "he can stay as long as you need us to keep him," then he was back on my doorstep less than 24 hours after getting back home from the hospital (and she wanted to bring him earlier but it was too inconvenient to drive him home at the time).
I brought them to see and visit with her.
You brought them. You, not she came and visited. This is such a common theme in my life. I am expected to set things up. I'm supposed to bring them to her house. And if she wants to see them and we make her pick them up, she acts like we should be so thankful she's so willing to come all this way (25 min drive) to see them.
There are definitely plenty of people here who understand what you're going through and are willing to listen to whatever it is you need to let out.
