I love the different perspective. The idea of the childhood trauma is we attract those that help us relive subcounscioulsy what we were use to as a child. It facinates me in a sense. If you look at it as the rational "adult" you see's it for what it is, but the child in you what makes you pull towards her, its the unresolved childhood trauma. Maybe not with everyone, but with me. Sometimes people meet a personality disordered person and can get trauma bonded without any childhood trauma.

What causes the bond is the good/bad behavior that creates the bond.

I'm like you, I'm not sure what she is. But there is some form of cluster B personaity disorder I'd say, hell, I might have a hint of BPD, not sure. but most likely PTSD and Codpendency from childhood trauma.
