It'snotme567, it doesn't sound like projection to me but it seems like push and pull and a need to isolate you from your family. I will give you an example of projection my ex used. The BPDex made a really mean comment to her mom as her mom walked by I saw the hurt in her eyes (still makes me sad to think about.) Then a couple of days later she told me I am so mean to my Mom. Before knowing about BPD and projection, I was just stunned at her thinking. If she was projecting her relationship with her deceased parents onto you, you would see her actions being placed on you but it's BPD so who knows.
Here's another one: my ex liked to call me childish, which I actually take as a compliment, since when we mature we add adult to the child and not replace it, and I had, and have, ready access to my inner 10 year old. But the point is she saw herself as drastically immature, emotionally stunted, to the point she looked up to her 17 year old daughter and 27 year old son as sources of wisdom and maturity. She didn't like the way that felt and knew she had issues, so offing it on me was a way to soothe herself, and is a lot easier than growing up.
