And I barely touched on the abuse part. She did not want to go there. I asked her how things are at home. I’m sure it’s difficult with your dad and brother. She said everything is fine and cut me off.
I really feel for you Kat.
This reaction from your DD may be the only safe way for her to react. In the case of my stbxuPDh, he repeatedly told me throughout the years that I wasn't allowed to talk about him to anyone. He told me if I did, he would find out. He had ways. I believed him. If anyone, even my mom, asked me how he was, if he mistreated me, etc, I would have said No. I would have said things were fine. I would have changed the subject.
My kids also believe him and fear his wrath. They refuse to open up to anyone about their dad - DS has been talking to his T, DD, only started talking to her T, but doesn't describe the bad behaviors. They've told me why - he will find out. They will be punished/cut off/ST. They are terrified to say anything to the GAL because their dad will find out. They would rather endure the abuse than reach out for help. It's heartbreaking, but there is nothing I can do but be here for them and support them.
The PD's love is conditional, and I think deep down the kids can sense this. Our love is not. They know we will always be there for them. So we become their dumping ground, they shun us for the PD, they do the PD's bidding, even though it hurts us. Why? Because, after all is said and done, we will still be there for them. It sucks. It really does. But I tell myself it's worse for the kids. Hang in there. We are here for you.

oh - I wanted to add that despite her reaction, your DD was listening to you. I try to talk openly with DS about certain things and I get shut down. But later on (days or weeks) he says something that indicates he was listening - he just had to go off on his own to process what I said and draw his own conclusions. So despite your DD brushing you off, know that she heard you, but that it was/is too painful for her to open up to you right now. But in broaching the subject - she now knows you are aware and that you are in her corner. Give her some time.
