The book quoted in the article, The Body Keeps the Score: Brain, Mind, and Body in the Healing of Trauma by Bessel van der Kolk MD, explains in detail why trauma bonding happens. It can be a heavy read with so much information, but if you go at a slow pace, it is easily understandable. Most libraries carry it, if you're doesn't, its about $15 for an ebook on Amazon. Well worth the money if you are looking for the answer to "why does trauma bonding happen?"
